The Wages program shown in Listing 5.2 uses an if-else statement to com-
pute the proper payment amount for an employee.
In the Wages program, if an employee works over 40 hours in a week, the
payment amount takes into account the overtime hours. An if-else statement is
used to determine whether the number of hours entered by the user is greater than
40. If it is, the extra hours are paid at a rate one and a half times the normal rate.
If there are no overtime hours, the total payment is based simply on the number
of hours worked and the standard rate.
Let's look at another example of an if-else statement:
if (roster.getSize() == FULL)
roster.expand();
else
roster.addName (name);
