C++ Program to Implement a Class Date

This C++ program implements a class – Date. The class uses time header contains a function time() which returns current calender time as an object of type time_t. We can extract various information from this struct by using -> with the pointer to the time structure.

Here is the source code of the C++ program implements a class – Date. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.
