Upcasting in c++

Upcasting and downcasting are an important part of C++. Upcasting and downcasting give a possibility to build complicated programs with a simple syntax. It can be achieved by using Polymorphism.

Downcasting is an opposite process, which consists of converting base class pointer (or reference) to derived class pointer.
