Question: 1.why do we need encapsulation?
2. what is a class in C++ analogous to in C

Answer: Analogue of C++ class in C:

We can have object-oriented implementation in C, by having a global function which implements all the interfaces of an object.The particular function will use local data-structures and locally declared functions, which will be accessible only inside the gobal function not outside it.

The locally declared functions can be get-set methods or any sort of manipulation of the locally defined data-structure.

The global function itself acts like the class.

The object creation and manipulation will be handled by this function alone.
