the string " AM", and then ended. Then, there is an else if statement that only occurs when the value of hour is equal to the value of hoursPerHalfDay.
When this condition is met, the value of hour is concatenated with the string " PM". Then another else if is made. This time the condition is
when both hour is greater than hoursPerHalfDay (12) and less than hoursPerDay (24). When these two things occur, the value of hour minus 12 is
concatenated with the string " PM". Then the last else if condition is made. The condition for this one is when the value of hour equals hoursPerDay.
When this condition is met, the value of hour minus 12 is concatenated with the sting " AM".
