If structure can be used in cpp so why there are classes in cpp?

Answer 1

I agree with Gamma. C++ can't afford to forget its legacy due to the fact that we are still dealing with some legacy code written in C++. But class introduced by C++ and as you know has some minor differences compared to structure. the following link is a discussion about that matter and worth to see.

Answer 2

It's a question that arises many times , actually when c was created , it had structures , but no classes ,but when they introduced classes , they thought of keeping it . So they didn't remove it , that's only the reason . Nothing else .

Answer 3

because C with classes (C++) was developed for the use of classes
