Classes in c++ - Classes (C++ only) A class is a mechanism for creating user-defined data types. It is similar to the C language structure data type. In C, a structure is composed of a set of data members. In C++, a class type is like a C structure, except that a class is composed of a set of data members and a set of operations that can be performed on the class.

 
C++ Class. A class is a blueprint for the object. We can think of a class as the technical design (prototype) of a car. It contains all the details about the brand, model, mileage, etc. We can then build different cars based on these descriptions. Here, each distinct car is an object. An example for this can be: A class named Car . Wind wall
