Construct a class Time with data members as hours, minute and second. Implement constructors, overloaded constructors and destructors for the same.

 /*

Definition : Construct a class Time with data members as hours, minute and

second. Implement constructors, overloaded constructors and destructors for

the same. Implement a overloaded operator ++ which will increment the time

by one second. Write a function display() to print hours, minute and second.

Assume that 24 hours clock.
