Design and implement an ADT that represents the time of day. Represent the time as hours and minutes on a 24-hour clock. The hours and minutes are the private data members of the class that implements the ADT. Include at least two initialization operations: one that provides a default value for the time, and another that sets the time to a client-supplied value. These operations are the class's constructors. Also include operations that set the time, increase the present time by a number of minutes, and display the time in 12-hour and 24-hour notations.
