Complete Modern C++ - Project - Part VIII (Upcasting and Downcasting)

The video tutorial explains the concepts of upcasting and downcasting in object-oriented programming. It describes how a base class can represent any of its child class objects through pointers or references, and introduces the concept of object slicing, where the compiler removes parts of a child object to fit it into a base class object. The tutorial provides examples to illustrate these concepts and discusses the potential for memory corruption if object slicing is not handled correctly. It also covers the need for manual intervention when performing downcasting, as opposed to the automatic nature of upcasting.
