I may be missing the point on your question but C is a compiled language.

To run it you have to:

(a) compile the C source into object files
(b) link the object files with libraries to produce the executable

once you have done that you can run the executable as many times as you like, and you can call it whatever name you like.

It is also compiled specific to the computer's architecture, so you can't expect 386 code to run natively on an UltraSparc. Similarly it is operating system dependent.
