C – Basic Program (JNNC Technologies)

A Simple C Program :

Every C program must have one special function main (). This is the point where execution begins when the program is running. We will see later that this does not have to be the first statement in the program, but it must exist as the entry point. The group of   statements defining the main () enclosed in a pair of braces ({}) are executed sequentially. Each expression statement must end with a semicolon.  The closing brace of the main function signals the end of the program. The main function can be located anywhere in the program but the general practice is to place it as the first function.

Here is an elementary C program.
