Expressions
From cppreference.com
An expression is a sequence of operators and their operands, that specifies a computation.
Expression evaluation may produce a result (e.g., evaluation of 2 + 2 produces the result 4) and may generate side-effects (e.g. evaluation of std::printf("%d", 4) prints the character '4' on the standard output).
Each C++ expression is characterized by two independent properties: A type and a value category.

- value categories (lvalue, rvalue, glvalue, prvalue, xvalue(since C++11)) classify expressions by their values
- order of evaluation of arguments and subexpressions specify the order in which intermediate results are obtained
