// Parameters: clockNumber - The unique employee ID
// Returns: hoursWorked - hours worked in a given week

// 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
