Complete Modern C++ - Value Categories

The video tutorial explains the concepts of L values and R values in programming, highlighting their differences and uses. It discusses how expressions return either L or R values and the persistence of these values. The tutorial also covers functions that return by reference or by value, introducing L and R value references in C++11. Examples are provided to illustrate R value references, and the video concludes with a discussion on function overloading using these references, emphasizing the detection of temporaries and the implementation of move semantics.
