Question

Design and implement a "Time" class (ADT-abstract data type) that represents a specific time of day. You can a object's hour, minutes and seconds as integers (for example, 10:23:15. is simplest to store these data member values in 24-hour "Military" me (e.g., 0:00:00 23:59:59) This data must be in the private section of the Time class that implements the ADT. In all cases throughout your Time object implementation, you must ensure and validate that these data member values are within their legitimate ranges. Include two initialization operation(s) (e.g., constructors) in your class a "convert constructor" uses client-supplied "24-hour" values for the ADT's data (be sure to validate the time data. Illegal values should result in same initialization as the default constructor) Example: Tine myAppt 15, o, o 3 o'clock in the afternoon a "default constructor" automatically initializes the Time object with the current time on the computer e Example: Time rightNow This current-time initialization can be accomplished in your code by using the built-in
