How to Compile and Run C program in Terminal

Compiling and running C programs on Windows requires a proper C compiler and access to the system terminal. With MinGW (a Windows-friendly version of the GCC compiler), users can easily convert their C source code into executable files using the Command Prompt. This article will guide you through installing MinGW, configuring the environment, and compiling C programs directly from the terminal.

Key Highlights:

• Learn how to install and set up MinGW (GCC) on Windows
• Understand how to configure environment variables
• Use Command Prompt (CMD) to compile .c files into executables
• Run C programs without needing any GUI-based IDE

How to Compile and Run C Program in Terminal

To compile and run C programs on Windows, you need a compiler and a terminal. MinGW (Minimalist GNU for Windows) provides an easy-to-install GCC compiler that works perfectly with Command Prompt (CMD). Once set up, you can compile any .c file into an executable using simple commands.

Below is a step-by-step guide to install MinGW, configure system paths, and compile/run C programs effortlessly.

Step 1: Install MinGW (GCC Compiler)

Before running C programs, install a compiler that converts C source code into machine code.

• Visit the official MinGW download page.
• Download the installer and run it..

In MinGW Installation Manager, select the following packages:

• mingw32-base
• mingw-gcc-g++

• Go to Installation → Apply Changes.
• Wait for MinGW to install all required components.

Step 2: Add MinGW to the System PATH

Adding MinGW to the PATH allows you to use gcc from any folder in CMD.

• Press Windows Key → search Environment Variables.

• Open Edit the system environment variables.
• Click Environment Variables.
• Under System variables, select Path → click Edit.
• Click New → add:
  • Click OK three times to save and exit.

Step 3: Open Command Prompt

• Press Windows Key, search cmd.
• Right-click → Run as Administrator.

• Type:

• gcc --version

If MinGW is installed correctly, the GCC version will appear.

Step 4: Navigate to Your C Program Directory

Use the cd command to go to the folder containing your .c file

• Type "cd C:\MyPrograms" , Click Enter button.

Step 5: Compile the C Program Using GCC

Use this syntax to compile your program:

gcc filename.c -o filename.exe

Explanation:

• filename.c → your C source file
• -o filename.exe → creates an executable output file

Example:

gcc hello.c -o hello.exe

Step 6: Run the C program and see the output

Finally, run your program with:

• filename.exe

Example: hello.exe

Your C program output will now appear in the terminal.

It is Armstrong No.
