References are an important part of C++, and a little-known fact about references is that there are actually two types of references: l-value and r-value. In this course, explore those two reference types by learning how to use the syntax and semantics of r-value references to extend the lifespan of transient values. Then, implement the move assignment operator and move constructor, using r-value references as their input arguments, to reduce the number of unnecessary copies created in your C++ programs. Finally, work with Resource Acquisition Is Initialization (RAII) to use smart pointers as a way to bypass complex rules, such as the rule of three and the rule of five, allowing you to follow the simplest rule of all - the rule of 0.
