C++ Developer - Encapsulation: Data Members and Member Functions

This video tutorial introduces object-oriented programming concepts, focusing on encapsulation. It explains how to create a class in C++, define its data members and member functions, and use setters and getters for data access. The tutorial also covers access control with public and private keywords and demonstrates how to refactor code for efficiency using pass by reference and constant references. A challenge is presented to reinforce learning.
