public is an access-modifier that allows you to access methods or properties of a class from outside of the class. A method or property set to protected can only be accessed from within the creating class or subclasses, while a private method or property can only be accessed from within that class
Any values that are marked as 'public' as a class member are global, and therefore accessible to any code in a c++ program. Since this defeats encapsulation, it isn't a good idea. You want to have the class public members maintain control of what will be allowed for changing class data members, not arbitrary code.

Is there anything similar between C and C plus plus with reference to data hiding?
No. Data hiding is a feature of object oriented programming. C does not support OOP, and therefore has no private member access. All members are public in C.

B plus b plus b plus c plus c plus c plus c equals?
b + b + b + c + c + c + c = 3b + 4c
Why you use public mode in c plus plus?
To expose an interface to the class members. Without an interface of some kind, an object would be useless.
