Question
Design a class called Date. The class should store a date in three integers: month, day, and year. There should be member functions to print the date in the following forms: 12/25/2014 December 25, 2014 25 December 2014 Demonstrate the class by writing a complete program implementing it. Input Validation: Do not accept values for the day greater than 31 or less than 1. Do not accept values for the month greater than 12 or less than 1.
