How to call a C program in shell script?

Question

I have a simple question. I want to execute a C program in a shell script. How do I do that? Thanks for your help in advance.

Answer 1

cc hello_world.c #produces a.out
./a.out #run your program

IMHO, your problem is the $PATH. Your current directory is not in PATH, so when you enter

a.out

your shell respond:

-bash: a.out: command not found

you should execute it as

./a.out

(or add "." to your PATH, but this is not recommended.)
