C/C++ :: Program Using Multiple Functions That Will Calculate Salary?

I already wrote a program that will calculate the gross pay for a set of employees.

I want modify the code by adding multiple functions.

I want to create a separate function whenever possible to break up the program.

For example, I would like have a function for obtaining the hours from the user, another function for calculating overtime hours, another for calculating gross pay and another function for producing the output.

#include <stdio.h>
#include <stdlib.h>
#define STD_HOURS 40.0
#define OT hour>STD_HOURS
#define SIZE 5
int main() {
int clockNumber[SIZE] = {98401, 526488, 765349, 34645, 127615}; /* employee ID */

[code]....
