Difference between private, public and protected inheritance in C++

To all you cpp experts, In c++ inheritance, 

class B : public A {
};

I am just curious why is the keyword public needed here? Does it mean something?

It means public members in A are inherited by B and are also public from B .

The alternatives are:

  • protected - public members from A are made protected in B , others are kept the same.

  • private - all members from A are made private in B .

    • The rules don't apply to methods that are hidden or overriden.
