Abstract

This chapter seeks to provide a deeper understanding of C++'s strong typing system and shows how expressions are evaluated and converted.

Operators are special kinds of functions that perform calculations on operands and return results.
Operands are the arguments supplied to an operator.

Operators can be thought of as ordinary functions, except that you can call some of them using infix operator symbols (e.g., +, -, *, /, etc.).

An expression can consist of a single operand, multiple operands with operators interspersed, or functions with arguments.
Each expression has a type and a value.
The value is obtained by applying the definitions of the operators (and/or functions) to the operands (and/or arguments).
