Answer / ashish raghuvanshi
Basically in C++ structure and class are same but with some
minor diffrences listed below:-
1. In classes all the members by default are private but in
structure members are public by default.
2. There is no term like constructor and destructor for
structs, but for class compiler creates default if you
don't provide.
