1. Assuming a variable areaCode is of type int, one solution is to print a leading zero if the area code is less than 100:
if (areaCode << 100)
cout << 0;
cout << areaCode;
Another solution is to declare an area code to be a string rather than an int, thereby reading or printing exactly three characters each time I/O takes place.

1. a. if ( !time1.Equal(time2) )
n = 1;
b.if (timel.LessThan(time2) || timel.Equal(time2))
n = 5;
c. if (time2.LessThan(timel))
n = 8;
d. if ( !timel.LessThan(time2) )
n = 5;
or
if (time2.LessThan(timel) || time2.Equal(time1))
n = 5;
3. Function specification (within the TimeType class declaration):
void WriteAmPm() const;
// Postcondition:
// Time has been output in 12-hour form
// HH:MM:SS AM or HH:MM:SS PM
Function definition (omitting the postcondition to save space):
