C++ is an object-oriented programming language. Even though it’s not pure, c++ language mainly deals with the OOPS concept. The classes and objects are the most important feature of C++ that leads to Object-Oriented programming. Class is the user-defined data type, which holds its data members and member functions, which can be accessed and used by creating the instance of that class called objects. The variables inside the class definition are called data members, and the functions are called member functions.

Class and Object in C++

Class of animals, all animals can run, and they all have legs. So here running is behavior and legs are part of their characteristics. There are many different animals in this class with different names, but they all possess this behavior and characteristics.

Similarly, a class is just a blueprint, which declares and defines characteristics and behavior, namely the data members and member functions, respectively. And all the objects of this class will share these characteristics and behavior.
