// Purpose: Obtains input from user, the number of hours worked
// per employee and stores the result in a local variable
// that is passed back to the calling function.
//
// Parameters: clockNumber - The unique employee ID
//
// Returns: hoursWorked - hours worked in a given week
//

//**************************************************************
// Function: printHeader
//
// Purpose: Prints the initial table header information.
//
// Parameters: none
//
// Returns: void
//
//**************************************************************

//*************************************************************
// Function: printEmp
//
// Purpose: Prints out all the employee information in a
// nice and orderly table format.
//
// 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)
//
