There is no such thing as a static class in C++. The closest approximation is a class that only contains static data members and static methods. Static data members in a class are shared by all the class objects as there is only one copy of them in memory, regardless of the number of objects of the class. Rectangle r1, r2, r3; SPONSOR AD. So, these are objects. The object ‘r1’ will have length, breadth, area, perimeter, and so on. And ‘r2’ and ‘r3’ will also have the same things. So, each rectangular object is having everything whatever it is given in this design. This is how you can write the classes.Jan 12, 2024 · Creating and Using C++ Classes Declaring a Class in C++.
