Why we not go for private and protected Inheritance in c++ ?

[Nabeel Nazir]

class A
{
Protected:
void k();

};
Class B : Private A
{
void k();
};

//What is wrong in this code of c++, Why we not go for private and protected Inheritance in c++ ?

In the code sample, the keywords private and protected are not capitalized.

You use private inheritance to inherit the implementation of a class.

You use protected inheritance when the base class is incomplete and needs its implementation completed in the derived class. The derived class in this case used to be called a mix-in class.
