Hello.

I am a user of cygwin.

First, run the Cygwin, a window would be prompted, inside of which would be a command-line interface:

Use UNIX commands to move yourself to the right directory where your c codes reside:

>:pwd
>:your current location presented to you here
>: cd somedirectory
>: ls
>: . .. test.c

There you go, you are in the right postion

Now use the gcc compiler to generate executable file.
>: gcc test.c

If your code is fine, you would see nothing from the CLI, but you can check the result

>: ls
>: . .. test.c a.exe

Now the a.exe is the executable file generated by gcc compiler.

Run it:

>: ./a.exe






Note that if you installed Cygwin not properly, you might not have the gcc compiler in your cygwin environment. In this situation I suggest you reinstall cywgin and pay special attention to the time when you are asked to choose the applications. Make sure that the gcc is ticked. I am not quite sure if that is the default option.

And you can try using the cc compiler to run your code:

>: cc test.c
