If y'all've written or downloaded some C code on your Windows PC, you'll need to compile the code to turn it into an programme y'all tin can run. This simple wikiHow tutorial will walk you through compiling and running a C program from the Windows control prompt using MinGW, an like shooting fish in a barrel-to-install version of the GCC compiler.

Steps

i
Install MinGW, a simple C compiler. If you haven't already done so, y'all'll need to install a C compiler on your PC to compile the C program. Compiling the C code will plough the code into an executable C programme. MinGW is one of the easiest options to install for Windows:
- Download MinGW from https://sourceforge.net/projects/mingw.
- Double-click the downloaded file and follow the on-screen instructions to prepare the installation.
- When you become to the MinGW Installation Managing director window, you'll encounter several packages in the upper-correct panel.

- Click the Installation menu and select Apply Changes.
- Click Apply.

Add the compiler'south path to your system environment variables. This pace makes it easier to run the compiler from the command prompt, as you won't have to enter the full path to the GCC program.
- Press the Windows key and type environment. Click Edit the arrangement environment variables in the search results.

- If you already had a command prompt window open up, close information technology and open another so the path you added

Use the cd command to become to the directory where your C program is saved. For example, if the program you want to compile is in C:\MyPrograms, type cd C:\MyPrograms and press Enter.

Run the gcc control to compile your C program. The syntax you'll use is gcc filename.c -o filename.exe. This compiles the program and makes it executable.
- Replace filename.c with the name of the file containing your C code, and filename.exe with the name you want to requite the compiled program.
- Make sure you give the compiled program a name that ends with .exe.
- The -o flag specifies the output file.

Blazon the name of your new plan and printing ↵ Enter . For case, if you created a program called hello.exe, you tin can type hi or howdy.exe. This runs your C program from the command prompt.
