The friend keyword allows (in a one-way relationship) functions to access private variables of a class. The friend keyword can also (in a one way relationship) allow classes to access all of the private member variables of another class. ►YouTube Channel: https://www.youtube.com/c/MikeShah ►Please like and subscribe to help the channel!
