Setting up a C project in Visual Studio Code involves installing the right tools, configuring build and debug settings, and organizing your files. It’s not hard once you know the steps. Here’s how to do it properly.

Install Required Tools

Before creating a project, make sure you have the necessary software installed on your system.

• C Compiler: Install MinGW-w64 (on Windows), Clang (macOS), or GCC (Linux). For Windows, download MinGW-w64 via mingw-w64.org or use MSYS2.
• Visual Studio Code: Download and install from code.visualstudio.com.
• C Extension: Open VS Code, go to Extensions (Ctrl Shift X), and install “C/C ” by Microsoft.

After installation, add the compiler’s bin folder to your system’s PATH so VS Code can find it.

Create and Configure the Project

Start by setting up a clean project folder with the proper configuration files.

• Create a new folder for your project and open it in VS Code.
• Create a main.cpp file with a simple program to test:

#include <iostream>
int main() {
    std::cout </iostream>

• Press Ctrl Shift P, type C/C : Edit Configurations (UI), and set the correct compiler path (e.g., g .exe for MinGW).

Set Up Build Tasks

To compile your code, define a build task using a tasks.json file.

• In VS Code, go to Terminal → Configure Default Build Task.
• Select g .exe (or your compiler) as the default build provider.
• This creates a .vscode/tasks.json file. Modify it to look like this:

{
  "version": "2.0.0",
  "tasks": [
    {
      "type": "cppbuild",
      "label": "C/C  : g   build active file",
      "command": "g  ",
      "args": [
        "-g",
        "${file}",
        "-o",
        "${fileDirname}/${fileBasenameNoExtension}.exe"
      ],
      "options": {
        "cwd": "${workspaceFolder}"
      },
      "problemMatcher": ["$gcc"],
      "group": "build",
      "detail": "compiler: g  "
    }
  ]
}

Now press Ctrl Shift B to build the active file. An executable will be created in the same directory.

Enable Debugging with launch.json

To debug your C code, create a launch.json configuration.

• Go to Run and Debug (Ctrl Shift D), click “create a launch.json file”, and choose Default (GDB/LLDB).
• Edit the file so it points to your compiled executable:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "g   - Build and Debug Active File",
      "type": "cppdbg",
      "request": "launch",
      "program": "${fileDirname}/${fileBasenameNoExtension}.exe",
      "args": [],
      "stopAtEntry": false,
      "cwd": "${workspaceFolder}",
      "environment": [],
      "externalConsole": false,
      "MIMode": "gdb",
      "miDebuggerPath": "path/to/gdb.exe", // e.g., "C:\\mingw64\\bin\\gdb.exe"
      "setupCommands": [
        {
          "description": "Enable pretty printing",
          "text": "-enable-pretty-printing",
          "ignoreFailures": true
        }
      ],
      "preLaunchTask": "C/C  : g   build active file"
    }
  ]
}

Set breakpoints, press F5, and start debugging. The program will compile and run in debug mode automatically.

Basically just install the tools, configure tasks and launch settings, and you’re ready to write, build, and debug C in VS Code. It takes a few minutes but works well across platforms.
