C++ Class and Object Programs / Examples (Set 2)

In C++ programming, a class is a blueprint for the object, it is a user-defined data type where we can define our own data type with data members and member functions like a real-life object.

This section contains the C++ programs based on the Class and Object approach. Each program has the solved code, output, and explanation.
