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.
