You have to compile it, then run the compiled executable file:

gcc -o parm  parm.c
# this made a file called "parm" - that's what -o is for
./parm

The ./ thing in front of the file name is to make the shell look for the parm file in your current directory.

If you call your C source code a "script", you're going to confuse people. A script is generally shorthand for "shellscript", a file containing commands that link together in some way to perform a more complex task.

A script really just refers to a file written in any interpreted language, one of which C is most definitely not.
