Task 7.4: Download the file Communication.zip. Understand the code and change it so that 100 date objects are randomly generated in Sender class, passed via Coordinator class to Receiver class and then printed in the Receiver class.

Hint: Use the header file Date.h from Task 7.1 to generate date objects as you did in Task 7.2. These date objects can be stored in a vector for convenience of communication.

***CODE MUST BE IN C++
