explain structure if possible.

Answer 1

See
Structure is a collection of different datatypes...It can be used for many purposes..sparing that it does not support OOP. Check the lessons in CPP for a better idea.
Classes are exactly the same thing..except that they implement modern OOP features and such stuff like abstraction and polymorphism...which makes them more useful than structures.
