C++ Classes and Operator Overloading, Assignments of Object Oriented Programming

AMET UniversityObject Oriented Programming

This document showcases a c++ code snippet demonstrating the concept of classes, constructors, and operator overloading. The code defines two classes 'a' and 'b' with their respective data members and member functions. The 'a' class includes an integer member 'c' and defines constructors, display function, pre-increment operator, and post-decrement operator. The 'b' class includes an integer member 'd' and defines constructors, display function, and pre-increment operator. The main function initializes instances of both classes, performs various operations, and displays the results.
