CS265 Programming in C++

Week 5 Assignment

Make a program to convert the time from 24-hour notation to 12-hour notation

and vice versa. Your program must be menu driven, giving the user the choice of

converting the time between the two notations. Furthermore, your program must

contain at least the following functions: a function to convert the time from

24-hour notation to 12-hour notation, a function to convert the time from 12-hour

notation to 24-hour notation, a function to display the choices, function(s) to

get the input, and function(s) to display the results. (For 12-hour time notation,

your program must display AM or PM).
