[newbie] executing programs

[M L Cates]

I am trying to learn how to do some C programming and my question is this: How
do I execute the program after it is compiled?  I have tried typing the name
of the program in at the prompt and it says "command not found".  I have tried
to type "sh" before the filename and am told "cannot execute binary file".

Any help would be appreciated, also, what does the "sh" before a filename do?
