CS12 Lab 3

Week of October 15—19

This lab deals with adding methods to a user defined class.

To Do

• Use the time class in your book. Copy the files time3.h and time3.cpp on pp 423-424 in the book (or just download them by clicking on the links).

• Open a new project and include both files in it.
  

• Add a new member function o the Time class, called tick() , that increments the time stored in a time object by one second. Be sure to check that the values of the data members second, minute, and hour contain legal values after this operation.
  

• Write a short main program (in a separate file), that tests the new method. The program should declare Time objects with the following values: 2:35:17, 15:21:59, 8:59:59, and 23:59:59. Your program should apply the tick() method to each of these objects, and print the new value of the object.

• Compile and run the project and verify correct output (the new time values should be 2:35:18, 15:22:00, 9:00:00, and 0:0:0).
  

Extra Credit

• Add another method, tick(int add), that increments the time value by add seconds (rather than one second).
