//**************************************************************
// Function: getHours
//
// 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 information for an employee
// in a nice and orderly table format.
//
// Parameters:
//
// clockNumber - unique employee ID
// wageRate - hourly wage rate
// hours - Hours worked for the week
// overtimeHrs - overtime hours worked in a week
// grossPay - gross pay for the week
//
// Returns: void

// Parameters:

// hours - Hours worked for the week
//
// Returns: float

// Function: calculateGrossPay
//
// Purpose: calculates the total earn of a worker
// based on their total work hours, and wage
//
// Parameters:
//
// wageRate - hourly wage rate
// hours - Hours worked for the week
// overtimeHrs - overtime hours worked in a week
//
// Returns: float
