Question 6- Implement a class called Time that has separate int member data for hours, minutes and seconds. One constructor should initialize this data to 0, and another should initialize it to fixed values. A member function should display it in 11:59:59 format. A member function named add() should add two objects of type time passed as arguments. A main () program should create two initialized values together, leaving the result in the third time variable. Finally it should display the value of this third variable.
