🔧 Setup C Language in VS Code (Step-by-Step Guide)

📌 What is C Language?

C is a powerful and fast programming language. But it needs to be compiled before running, unlike Python or JavaScript.

🛠️ Tools You Need to Install

• Visual Studio Code (VS Code) – For writing code
• MinGW Compiler (GCC) – For compiling and running C programs
• C/C++ Extension in VS Code – For IntelliSense and debugging

📥 Step 1: Install MinGW (C Compiler)

1. Go to MinGW-w64 Download (SourceForge)
2. Download and open
3. Click install
4. Click Continue
5. Right click and select following :
   1. mingw-develope-toolkit
   2. mingw32-base
   3. mingw32-gcc-g++
   4. mingw32-gcc-objc
   5. msys-base
6. Go to installation (top-left corner of the window) and click "apply changes"
7. Close all windows
8. Go to "My PC" and open your "C Drive"
9. Open MinGW and open bin folder
10. Copy the path from above
11. Open system environment variables and paste that path creating as new path
12. open cmd and check version : g++ --version

🔗 Step 2: Add GCC to System PATH

Without this step, the terminal won’t recognize the gcc command.

1. Search for Environment Variables in Windows Search
2. Click Edit the system environment variables
3. Click Environment Variables...
4. Under System Variables, select Path → Click Edit
5. Click New and paste:

   C:\Program Files\mingw-w64\mingw64\bin

6. Click OK on all windows and restart your computer

🧪 Step 3: Check if GCC Works

Open your Command Prompt or VS Code Terminal and run:

gcc --version

If it shows the version, you’re ready to go!

💻 Step 4: Setup VS Code

1. Open VS Code
2. Install the extension: C/C++ by Microsoft
3. Create a folder, then a file called hello.c
4. Write this basic program:

#include <stdio.h>

int main() {
  printf("Hello, World!\n");
  return 0;
}
      

🏃‍♂️ Step 5: Compile and Run

1. Open Terminal in VS Code (Ctrl + `)
2. Type:

   gcc hello.c -o hello

3. Run it:

   ./hello

   If you're on Windows:

   hello.exe

🐞 Common Errors and Fixes

• 'gcc' is not recognized: You forgot to install MinGW or add to PATH
• Permission denied: Use correct file names and paths
• Output not showing: Make sure you compile before running

🎉 You're Done!

Congratulations! You now have C running on your computer like a pro coder! 🚀
