function printf should have a prototype And the following warning : Function should return a value. I am referring the book Programming in ANSI C by E. Balaguruswamy. In the book, this is the first sample program. And I just cannot run the very first program. So, please help.

A prototype declares the function name, its parameters, and its return type to the rest of the program prior to the function's actual declaration.
