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.

C/C++ compiler and debugger

The C/C++ extension does not include a C++ compiler or debugger. You will need to install these tools or use those already installed on your computer.
Apr 21, 2017 This blog post goes over the following concepts: Setting Up Visual Studio. Opening Projects or Folders of Code. Building the Application. Code Editing & Navigation. Debugging and Diagnosing Issues. Working With A Team. How to use Dev-C These are the recommended requirements of Dev-C: Microsoft Windows 98, NT or 2000. Dev-C allows you to write, compile and run a C or C program. C programming language is an enhanced version of C language that provides. Compile Compile and run. New source file Run.
Popular C++ compilers are:
- GCC on Linux
- GCC via Mingw-w64 on Windows
- Microsoft C++ compiler on Windows
- Clang for XCode on macOS
Make sure your compiler executable is in your platform path so the extension can find it. You can check availability of your C++ tools by opening the Integrated Terminal (⌃` (Windows, Linux Ctrl+`)) in VS Code and try running the executable (for example g++ --help).
Install the Microsoft C/C++ extension
- Open VS Code.
- Click the Extensions view icon on the Sidebar (⇧⌘X (Windows, Linux Ctrl+Shift+X)).
- Search for
c++. - Click Install.
Hello World tutorials
Get started with C++ and VS Code with Hello World tutorials for your environment:
Documentation
You can find more documentation on using the Microsoft C/C++ extension under the C++ section, where you'll find topics on:
Remote Development
VS Code and the C++ extension support Remote Development allowing you to work over SSH on a remote machine or VM, inside a Docker container, or in the Windows Subsystem for Linux (WSL).
To install support for Remote Development:
- Install the VS Code Remote Development Extension Pack.
- If the remote source files are hosted in WSL, use the Remote - WSL extension.
- If you are connecting to a remote machine with SSH, use the Remote - SSH extension.
- If the remote source files are hosted in a container (for example, Docker), use the Remote - Containers extension.
Feedback
If you run into any issues or have suggestions for the Microsoft C/C++ extension, please file issues and suggestions on GitHub. If you haven't already provided feedback, please take this quick survey to help shape this extension for your needs.
C++ is a language that has evolved much over the years, and these tutorials explain many features added recently to the language. Therefore, in order to properly follow the tutorials, a recent compiler is needed. It shall support (even if only partially) the features introduced by the 2011 standard.
Many compiler vendors support the new features at different degrees. See the bottom of this page for some compilers that are known to support the features needed. Some of them are free!
If for some reason, you need to use some older compiler, you can access an older version of these tutorials here (no longer updated).
What is a compiler?
Computers understand only one language and that language consists of sets of instructions made of ones and zeros. This computer language is appropriately called machine language.A single instruction to a computer could look like this:
Dev C++ Code Examples
| 00000 | 10011110 |
A particular computer's machine language program that allows a user to input two numbers, adds the two numbers together, and displays the total could include these machine code instructions:
Dev C++ Tutorial
| 00000 | 10011110 |
| 00001 | 11110100 |
| 00010 | 10011110 |
| 00011 | 11010100 |
| 00100 | 10111111 |
| 00101 | 00000000 |
As you can imagine, programming a computer directly in machine language using only ones and zeros is very tedious and error prone. To make programming easier, high level languages have been developed. High level programs also make it easier for programmers to inspect and understand each other's programs easier.
This is a portion of code written in C++ that accomplishes the exact same purpose:
Even if you cannot really understand the code above, you should be able to appreciate how much easier it will be to program in the C++ language as opposed to machine language.
Because a computer can only understand machine language and humans wish to write in high level languages high level languages have to be re-written (translated) into machine language at some point. This is done by special programs called compilers, interpreters, or assemblers that are built into the various programming applications.
C++ is designed to be a compiled language, meaning that it is generally translated into machine language that can be understood directly by the system, making the generated program highly efficient. For that, a set of tools are needed, known as the development toolchain, whose core are a compiler and its linker.
Console programs
Console programs are programs that use text to communicate with the user and the environment, such as printing text to the screen or reading input from a keyboard.Console programs are easy to interact with, and generally have a predictable behavior that is identical across all platforms. They are also simple to implement and thus are very useful to learn the basics of a programming language: The examples in these tutorials are all console programs.
The way to compile console programs depends on the particular tool you are using.The easiest way for beginners to compile C++ programs is by using an Integrated Development Environment (IDE). An IDE generally integrates several development tools, including a text editor and tools to compile programs directly from it.
Here you have instructions on how to compile and run console programs using different free Integrated Development Interfaces (IDEs):
| IDE | Platform | Console programs |
|---|---|---|
| Code::blocks | Windows/Linux/MacOS | Compile console programs using Code::blocks |
| Visual Studio Express | Windows | Compile console programs using VS Express 2013 |
| Dev-C++ | Windows | Compile console programs using Dev-C++ |
If you happen to have a Linux or Mac environment with development features, you should be able to compile any of the examples directly from a terminal just by including C++11 flags in the command for the compiler:
| Compiler | Platform | Command |
|---|---|---|
| GCC | Linux, among others... | g++ -std=c++0x example.cpp -o example_program |
| Clang | OS X, among others... | clang++ -std=c++11 -stdlib=libc++ example.cpp -o example_program |
