    Don't post pictures of code. Post your code as properly formatted text into the question. Before doing so read this: [ask] – Jabberwocky Apr 16 '21 at 08:11

    Hint: `argc` and `argv` in `main()`. That's *exactly* what they're for. `prog.exe blah blah`. – tadman Apr 16 '21 at 08:12

I guess that you want to pass the argument to prog.exe and not to gcc, then

gcc -c -g -Wall calc_statistics.c gcc -o prog.exe && ./prog.exe "$1"

That is, compile the program and if there are no error run it with the argument.

It's not very efficient to compile the program every time the script runs so you can move gcc out.

You can also check your script using shellcheck.
