Introduction This talks about Virtual Friend Function in C++. Background Friend functions are not in-herited in C++. So, to achieve dynamic binding with friend functions, we have to make the interfaces as virtual (make it as protected part of class) to operate within the friend function....

A virtual function is used where we want to allow the derived class to replace the implementation of the same function in base class. The compiler always calls the derived class function when called with object of the derived class or an object of base class holding the address of the derived class...

Being an experienced C/C++ developer, sometimes there are modules in which the code layer which interact with the system is written in C while the layer above it is written in C++. Have you ever thought of how these two layers (one written in C and other in C++) interact? What if we want to call a...
