Core C++ 2019 :: Dan Saks :: Understanding Lvalues and Rvalues
You've probably heard the terms lvalue and rvalue, if only because they occasionally appear in compiler error messages. However, if you have only a vague understanding of what they mean, you're not alone. Lvalues and rvalues aren't actually language features, but rather semantic properties of expressions and sub-expressions. Understanding lvalues and rvalues provides valuable insights into the behavior of built-in operators, the code generated to execute those operators, and the meaning of some otherwise cryptic compiler error messages. Also, understanding lvalues and rvalues is essential background for working effectively with reference types and overloaded operators. This session covers what you need to know about lvalues and rvalues in C++.
