// Returns: hoursWorked - hours worked in a given week

// Parameters: 
//
//     clockNumber - Array of employee clock numbers
//     wageRate - Array of employee wages per hour
//     hours - Array of number of hours worked by an employee
//     overtimeHrs - Array of overtime hours for each employee
//     grossPay - Array of gross pay calculations for each employee
//     theSize - Number of employees to process 
// 
// Returns: Nothing (call by reference)
//
