  1. Jan 10, 2009  Thus far I have tried Borland, MS Visual Studio 2008 Express Edition, and Dev-C. I didn't like Borland at all. I felt the interface was cumbersom to use. Also, the editor did not indent as I wanted. And the straw that broke the camels back was that code I had written that worked on MS VS 2008 ED and Dev-C didn't always work on Borland.
  2. To use MSVC from a command line or VS Code, you must run from a Developer Command Prompt for Visual Studio. An ordinary shell such as PowerShell, Bash, or the Windows command prompt does not have the necessary path environment variables set. To open the Developer Command Prompt for VS, start typing 'developer' in the Windows Start menu, and you.

If you haven't downloaded and installed Visual Studio and the Visual C++ tools yet, here's how to get started.

Visual Studio 2019 Installation

Overview of C development in Visual Studio.; 5 minutes to read; In this article. As part of the Visual Studio Integrated Development Environment (IDE), Microsoft C (MSVC) shares many windows and tools in common with other languages. C/C for Visual Studio Code (Preview) C/C support for Visual Studio Code is provided by a Microsoft C/C extension to enable cross-platform C and C development on Windows, Linux, and macOS. The extension is still in preview and our focus is code editing, navigation, and debugging support for C and C code everywhere that VS Code runs. LeetCode Debugger for C.

Welcome to Visual Studio 2019! In this version, it's easy to choose and install just the features you need. And because of its reduced minimum footprint, it installs quickly and with less system impact.

Note

This topic applies to installation of Visual Studio on Windows. Visual Studio Code is a lightweight, cross-platform development environment that runs on Windows, Mac, and Linux systems. The Microsoft C/C++ for Visual Studio Code extension supports IntelliSense, debugging, code formatting, auto-completion. Visual Studio for Mac doesn't support Microsoft C++, but does support .NET languages and cross-platform development. For installation instructions, see Install Visual Studio for Mac.

Want to know more about what else is new in this version? See the Visual Studio release notes.

Ready to install? We'll walk you through it, step-by-step.

Step 1 - Make sure your computer is ready for Visual Studio

Before you begin installing Visual Studio:

  1. Check the system requirements. These requirements help you know whether your computer supports Visual Studio 2019.

  2. Apply the latest Windows updates. These updates ensure that your computer has both the latest security updates and the required system components for Visual Studio.

  3. Reboot. The reboot ensures that any pending installs or updates don't hinder the Visual Studio install.

  4. Free up space. Remove unneeded files and applications from your %SystemDrive% by, for example, running the Disk Cleanup app.

For questions about running previous versions of Visual Studio side by side with Visual Studio 2019, see the Visual Studio 2019 Platform Targeting and Compatibility page.

Step 2 - Download Visual Studio

Next, download the Visual Studio bootstrapper file. To do so, choose the following button, choose the edition of Visual Studio that you want, choose Save, and then choose Open folder.

Step 3 - Install the Visual Studio installer

Run the bootstrapper file to install the Visual Studio Installer. This new lightweight installer includes everything you need to both install and customize Visual Studio.

  1. From your Downloads folder, double-click the bootstrapper that matches or is similar to one of the following files:

    • vs_community.exe for Visual Studio Community
    • vs_professional.exe for Visual Studio Professional
    • vs_enterprise.exe for Visual Studio Enterprise

    If you receive a User Account Control notice, choose Yes.

  2. We'll ask you to acknowledge the Microsoft License Terms and the Microsoft Privacy Statement. Choose Continue.

Step 4 - Choose workloads

After the installer is installed, you can use it to customize your installation by selecting the workloads, or feature sets, that you want. Here's how.

  1. Find the workload you want in the Installing Visual Studio screen.

    For core C++ support, choose the 'Desktop development with C++' workload. It comes with the default core editor, which includes basic code editing support for over 20 languages, the ability to open and edit code from any folder without requiring a project, and integrated source code control.

    Additional workloads support other kinds of C++ development. For example, choose the 'Universal Windows Platform development' workload to create apps that use the Windows Runtime for the Microsoft Store. Choose 'Game development with C++' to create games that use DirectX, Unreal, and Cocos2d. Choose 'Linux development with C++' to target Linux platforms, including IoT development.

    The Installation details pane lists the included and optional components installed by each workload. You can select or deselect optional components in this list. For example, to support development by using the Visual Studio 2017 or 2015 compiler toolsets, choose the MSVC v141 or MSVC v140 optional components. You can add support for MFC, the experimental Modules language extension, IncrediBuild, and more.

  2. After you choose the workload(s) and optional components you want, choose Install.

    Next, status screens appear that show the progress of your Visual Studio installation.

Tip

At any time after installation, you can install workloads or components that you didn't install initially. If you have Visual Studio open, go to Tools > Get Tools and Features.. which opens the Visual Studio Installer. Or, open Visual Studio Installer from the Start menu. From there, you can choose the workloads or components that you wish to install. Then, choose Modify.

Step 5 - Choose individual components (Optional)

If you don't want to use the Workloads feature to customize your Visual Studio installation, or you want to add more components than a workload installs, you can do so by installing or adding individual components from the Individual components tab. Choose what you want, and then follow the prompts.

Step 6 - Install language packs (Optional)

By default, the installer program tries to match the language of the operating system when it runs for the first time. To install Visual Studio in a language of your choosing, choose the Language packs tab from the Visual Studio Installer, and then follow the prompts.

Change the installer language from the command line

Another way that you can change the default language is by running the installer from the command line. For example, you can force the installer to run in English by using the following command: vs_installer.exe --locale en-US. The installer will remember this setting when it's run the next time. The installer supports the following language tokens: zh-cn, zh-tw, cs-cz, en-us, es-es, fr-fr, de-de, it-it, ja-jp, ko-kr, pl-pl, pt-br, ru-ru, and tr-tr.

Step 7 - Change the installation location (Optional)

You can reduce the installation footprint of Visual Studio on your system drive. You can choose to move the download cache, shared components, SDKs, and tools to different drives, and keep Visual Studio on the drive that runs it the fastest.

Important

You can select a different drive only when you first install Visual Studio. If you've already installed it and want to change drives, you must uninstall Visual Studio and then reinstall it.

Step 8 - Start developing

  1. After Visual Studio installation is complete, choose the Launch button to get started developing with Visual Studio.

  2. On the start window, choose Create a new project.

  3. In the search box, enter the type of app you want to create to see a list of available templates. The list of templates depends on the workload(s) that you chose during installation. To see different templates, choose different workloads.

    You can also filter your search for a specific programming language by using the Language drop-down list. You can filter by using the Platform list and the Project type list, too.

  4. Visual Studio opens your new project, and you're ready to code!

Visual Studio 2017 Installation

In Visual Studio 2017, it's easy to choose and install just the features you need. And because of its reduced minimum footprint, it installs quickly and with less system impact.

Prerequisites

  • A broadband internet connection. The Visual Studio installer can download several gigabytes of data.

  • A computer that runs Microsoft Windows 7 or later versions. We recommend Windows 10 for the best development experience. Make sure that the latest updates are applied to your system before you install Visual Studio.

  • Enough free disk space. Visual Studio requires at least 7 GB of disk space, and can take 50 GB or more if many common options are installed. We recommend you install it on your C: drive.

For details on the disk space and operating system requirements, see Visual Studio Product Family System Requirements. The installer reports how much disk space is required for the options you select.

Download and install

  1. Download the latest Visual Studio 2017 installer for Windows.

    Tip

    The Community edition is for individual developers, classroom learning, academic research, and open source development. For other uses, install Visual Studio 2017 Professional or Visual Studio 2017 Enterprise.

  2. Find the installer file you downloaded and run it. It may be displayed in your browser, or you may find it in your Downloads folder. The installer needs Administrator privileges to run. You may see a User Account Control dialog asking you to give permission to let the installer make changes to your system; choose Yes. If you're having trouble, find the downloaded file in File Explorer, right-click on the installer icon, and choose Run as Administrator from the context menu.

  3. The installer presents you with a list of workloads, which are groups of related options for specific development areas. Support for C++ is now part of optional workloads that aren't installed by default.

    For C++, select the Desktop development with C++ workload and then choose Install.

  4. When the installation completes, choose the Launch button to start Visual Studio.

    The first time you run Visual Studio, you're asked to sign in with a Microsoft Account. If you don't have one, you can create one for free. You must also choose a theme. Don't worry, you can change it later if you want to.

    It may take Visual Studio several minutes to get ready for use the first time you run it. Here's what it looks like in a quick time-lapse:

    Visual Studio starts much faster when you run it again.

  5. When Visual Studio opens, check to see if the flag icon in the title bar is highlighted:

    If it's highlighted, select it to open the Notifications window. If there are any updates available for Visual Studio, we recommend you install them now. Once the installation is complete, restart Visual Studio.

Visual Studio 2015 Installation

To install Visual Studio 2015, go to Download older versions of Visual Studio. Run the setup program and choose Custom installation and then choose the C++ component. To add C++ support to an existing Visual Studio 2015 installation, click on the Windows Start button and type Add Remove Programs. Open the program from the results list and then find your Visual Studio 2015 installation in the list of installed programs. Double-click it, then choose Modify and select the Visual C++ components to install.

In general, we highly recommend that you use Visual Studio 2017 even if you need to compile your code using the Visual Studio 2015 compiler. For more information, see Use native multi-targeting in Visual Studio to build old projects.

When Visual Studio is running, you're ready to continue to the next step.

Next Steps

In this tutorial, you configure Visual Studio Code to use the Microsoft Visual C++ compiler and debugger on Windows.

After configuring VS Code, you will compile and debug a simple Hello World program in VS Code. This tutorial does not teach you details about the Microsoft C++ toolset or the C++ language. For those subjects, there are many good resources available on the Web.

If you have any problems, feel free to file an issue for this tutorial in the VS Code documentation repository.

Prerequisites

To successfully complete this tutorial, you must do the following:

  1. Install Visual Studio Code.

  2. Install the C/C++ extension for VS Code. You can install the C/C++ extension by searching for 'c++' in the Extensions view (⇧⌘X (Windows, Linux Ctrl+Shift+X)).

  3. Install the Microsoft Visual C++ (MSVC) compiler toolset.

    If you have a recent version of Visual Studio, open the Visual Studio Installer from the Windows Start menu and verify that the C++ workload is checked. If it's not installed, then check the box and click the Modify button in the installer.

    You can also install just the C++ Build Tools, without a full Visual Studio IDE installation. From the Visual Studio Downloads page, scroll down until you see Tools for Visual Studio under the All downloads section and select the download for Build Tools for Visual Studio.

    This will launch the Visual Studio Installer, which will bring up a dialog showing the available Visual Studio Build Tools workloads. Check the C++ build tools workload and select Install.

Check your Microsoft Visual C++ installation

To use MSVC from a command line or VS Code, you must run from a Developer Command Prompt for Visual Studio. An ordinary shell such as PowerShell, Bash, or the Windows command prompt does not have the necessary path environment variables set.

To open the Developer Command Prompt for VS, start typing 'developer' in the Windows Start menu, and you should see it appear in the list of suggestions. The exact name depends on which version of Visual Studio or the Visual Studio Build Tools you have installed. Click on the item to open the prompt.

You can test that you have the C++ compiler, cl.exe, installed correctly by typing 'cl' and you should see a copyright message with the version and basic usage description.

If the Developer Command Prompt is using the BuildTools location as the starting directory (you wouldn't want to put projects there), navigate to your user folder (C:users{your username}) before you start creating new projects.

Create Hello World

From the Developer Command Prompt, create an empty folder called 'projects' where you can store all your VS Code projects, then create a subfolder called 'helloworld', navigate into it, and open VS Code (code) in that folder (.) by entering the following commands:

The 'code .' command opens VS Code in the current working folder, which becomes your 'workspace'. As you go through the tutorial, you will see three files created in a .vscode folder in the workspace:

  • tasks.json (build instructions)
  • launch.json (debugger settings)
  • c_cpp_properties.json (compiler path and IntelliSense settings)

Add a source code file

In the File Explorer title bar, select the New File button and name the file helloworld.cpp.

Add hello world source code

Now paste in this source code:

Now press ⌘S (Windows, Linux Ctrl+S) to save the file. Notice how the file you just added appears in the File Explorer view (⇧⌘E (Windows, Linux Ctrl+Shift+E)) in the side bar of VS Code:

You can also enable Auto Save to automatically save your file changes, by checking Auto Save in the main File menu.

The Activity Bar on the far left lets you open different views such as Search, Source Control, and Run. You'll look at the Run view later in this tutorial. You can find out more about the other views in the VS Code User Interface documentation.

Note: When you save or open a C++ file, you may see a notification from the C/C++ extension about the availability of an Insiders version, which lets you test new features and fixes. You can ignore this notification by selecting the X (Clear Notification).

Explore IntelliSense

In your new helloworld.cpp file, hover over vector or string to see type information. After the declaration of the msg variable, start typing msg. as you would when calling a member function. You should immediately see a completion list that shows all the member functions, and a window that shows the type information for the msg object:

You can press the Tab key to insert the selected member; then, when you add the opening parenthesis, you will see information about any arguments that the function requires.

Build helloworld.cpp

Next, you will create a tasks.json file to tell VS Code how to build (compile) the program. This task will invoke the Microsoft C++ compiler to create an executable file based on the source code.

From the main menu, choose Terminal > Configure Default Build Task. In the dropdown, which will display a tasks dropdown listing various predefined build tasks for C++ compilers. Choose cl.exe build active file, which will build the file that is currently displayed (active) in the editor.

This will create a tasks.json file in a .vscode folder and open it in the editor.

Your new tasks.json file should look similar to the JSON below:

The string class type introduced with Standard C. The C-Style Character String. The C-style character string originated within the C language and continues to be supported within C. This string is actually a one-dimensional array of characters which is terminated by a null character '0'. Thus a null-terminated string contains the characters that comprise the string followed by a null. How to input string in dev c++

The command setting specifies the program to run; in this case that is 'cl.exe'. The args array specifies the command-line arguments that will be passed to cl.exe. These arguments must be specified in the order expected by the compiler. This task tells the C++ compiler to take the active file (${file}), compile it, and create an executable file (/Fe: switch) in the current directory (${fileDirname}) with the same name as the active file but with the .exe extension (${fileBasenameNoExtension}.exe), resulting in helloworld.exe for our example.

Note: You can learn more about task.json variables in the variables reference.

The label value is what you will see in the tasks list; you can name this whatever you like.

The problemMatcher value selects the output parser to use for finding errors and warnings in the compiler output. For cl.exe, you'll get the best results if you use the $msCompile problem matcher.

The 'isDefault': true value in the group object specifies that this task will be run when you press ⇧⌘B (Windows, Linux Ctrl+Shift+B). This property is for convenience only; if you set it to false, you can still run it from the Terminal menu with Tasks: Run Build Task.

Running the build

  1. Go back to helloworld.cpp. Your task builds the active file and you want to build helloworld.cpp.

  2. To run the build task defined in tasks.json, press ⇧⌘B (Windows, Linux Ctrl+Shift+B) or from the Terminal main menu choose Tasks: Run Build Task.

  3. When the task starts, you should see the Integrated Terminal panel appear below the source code editor. After the task completes, the terminal shows output from the compiler that indicates whether the build succeeded or failed. For a successful C++ build, the output looks something like this:

  4. Create a new terminal using the + button and you'll have a new terminal (running PowerShell) with the helloworld folder as the working directory. Run ls and you should now see the executable helloworld.exe along with various intermediate C++ output and debugging files (helloworld.obj, helloworld.pdb).

  5. You can run helloworld in the terminal by typing .helloworld.exe.

Note: You might need to press Enter a couple of times initially to see the PowerShell prompt in the terminal. This issue should be fixed in a future release of Windows.

Code

Modifying tasks.json

You can modify your tasks.json to build multiple C++ files by using an argument like '${workspaceFolder}*.cpp' instead of ${file}. This will build all .cpp files in your current folder. You can also modify the output filename by replacing '${fileDirname}${fileBasenameNoExtension}.exe' with a hard-coded filename (for example '${workspaceFolder}myProgram.exe').

Debug helloworld.cpp

Next, you'll create a launch.json file to configure VS Code to launch the Microsoft C++ debugger when you press F5 to debug the program. From the main menu, choose Run > Add Configuration.. and then choose C++ (Windows).

You'll then see a dropdown for various predefined debugging configurations. Choose cl.exe build and debug active file.

VS Code creates a launch.json file, opens it in the editor, and builds and runs 'helloworld'.

The program setting specifies the program you want to debug. Here it is set to the active file folder ${fileDirname} and active filename with the .exe extension ${fileBasenameNoExtension}.exe, which if helloworld.cpp is the active file will be helloworld.exe.

By default, the C++ extension won't add any breakpoints to your source code and the stopAtEntry value is set to false. Change the stopAtEntry value to true to cause the debugger to stop on the main method when you start debugging.

Start a debugging session

  1. Go back to helloworld.cpp so that it is the active file.
  2. Press F5 or from the main menu choose Run > Start Debugging. Before you start stepping through the source code, let's take a moment to notice several changes in the user interface:

  • The Integrated Terminal appears at the bottom of the source code editor. In the Debug Output tab, you see output that indicates the debugger is up and running.

  • The editor highlights the first statement in the main method. This is a breakpoint that the C++ extension automatically sets for you:

  • The Run view on the left shows debugging information. You'll see an example later in the tutorial.

  • At the top of the code editor, a debugging control panel appears. You can move this around the screen by grabbing the dots on the left side.

Step through the code

Now you're ready to start stepping through the code.

  1. Click or press the Step over icon in the debugging control panel until the for (const string& word : msg) statement is highlighted.

    The Step Over command skip over all the internal function calls within the vector and string classes that are invoked when the msg variable is created and initialized. Notice the change in the Variables window on the left. In this case, the errors are expected because, although the variable names for the loop are now visible to the debugger, the statement has not executed yet, so there is nothing to read at this point. The contents of msg are visible, however, because that statement has completed.

  2. Press Step over again to advance to the next statement in this program (skipping over all the internal code that is executed to initialize the loop). Now, the Variables window shows information about the loop variables.

  3. Press Step over again to execute the cout statement. Note As of the March 2019 version of the extension, no output is displayed until the loop completes.

  4. If you like, you can keep pressing Step over until all the words in the vector have been printed to the console. But if you are curious, try pressing the Step Into button to step through source code in the C++ standard library!

    To return to your own code, one way is to keep pressing Step over. Another way is to set a breakpoint in your code by switching to the helloworld.cpp tab in the code editor, putting the insertion point somewhere on the cout statement inside the loop, and pressing F9. A red dot appears in the gutter on the left to indicate that a breakpoint has been set on this line.

    Then press F5 to start execution from the current line in the standard library header. Execution will break on cout. If you like, you can press F9 again to toggle off the breakpoint.

Set a watch

Visual

Sometimes you might want to keep track of the value of a variable as your program executes. You can do this by setting a watch on the variable.

  1. Place the insertion point inside the loop. In the Watch window, click the plus sign and in the text box, type word, which is the name of the loop variable. Now view the Watch window as you step through the loop.

  2. Add another watch by adding this statement before the loop: int i = 0;. Then, inside the loop, add this statement: ++i;. Now add a watch for i as you did in the previous step.

  3. To quickly view the value of any variable while execution is paused on a breakpoint, you can hover over it with the mouse pointer.

C/C++ configurations

If you want more control over the C/C++ extension, you can create a c_cpp_properties.json file, which will allow you to change settings such as the path to the compiler, include paths, C++ standard (default is C++17), and more.

You can view the C/C++ configuration UI by running the command C/C++: Edit Configurations (UI) from the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)).

This opens the C/C++ Configurations page. When you make changes here, VS Code writes them to a file called c_cpp_properties.json in the .vscode folder.

Visual Studio Code places these settings in .vscodec_cpp_properties.json. If you open that file directly, it should look something like this:

You only need to add to the Include path array setting if your program includes header files that are not in your workspace or in the standard library path.

Compiler path

The compilerPath setting is an important setting in your configuration. The extension uses it to infer the path to the C++ standard library header files. When the extension knows where to find those files, it can provide useful features like smart completions and Go to Definition navigation.

The C/C++ extension attempts to populate compilerPath with the default compiler location based on what it finds on your system. The extension looks in several common compiler locations.

The compilerPath search order is:

  • First check for the Microsoft Visual C++ compilerOpe
  • Then look for g++ on Windows Subsystem for Linux (WSL)
  • Then g++ for Mingw-w64.

If you have g++ or WSL installed, you might need to change compilerPath to match the preferred compiler for your project. For Microsoft C++, the path should look something like this, depending on which specific version you have installed: 'C:/Program Files (x86)/Microsoft Visual Studio/2017/BuildTools/VC/Tools/MSVC/14.16.27023/bin/Hostx64/x64/cl.exe'.

Reusing your C++ configuration

VS Code is now configured to use the Microsoft C++ compiler. The configuration applies to the current workspace. To reuse the configuration, just copy the JSON files to a .vscode folder in a new project folder (workspace) and change the names of the source file(s) and executable as needed.

Troubleshooting

Difference Between Dev C++ And Visual Studio

The term 'cl.exe' is not recognized

Visual Studio Code What Is

If you see the error 'The term 'cl.exe' is not recognized as the name of a cmdlet, function, script file, or operable program.', this usually means you are running VS Code outside of a Developer Command Prompt for Visual Studio and VS Code doesn't know the path to the cl.exe compiler.

Vs Code C++ Development

You can always check that you are running VS Code in the context of the Developer Command Prompt by opening a new Terminal (⌃⇧` (Windows, Linux Ctrl+Shift+`)) and typing 'cl' to verify cl.exe is available to VS Code.
