Question

Write a program that prompts the user to enter time in 12-hour notation. The program then outputs the time in 24-hour notation. Your program must contain three exception classes: invalidHr, invalidMin, and invalidSec. If the user enters an invalid value for hours, then the program should throw and catch an invalidHr object. Follow similar conventions for the invalid values of minutes and seconds.

This needs to be done in C++

There needs to be a separate header file for each invalidHr, invalidMin, invalidSec
