Appendix B. Operator Precedence
It is important to understand that operators have a precedence, but it is not essential to memorize the precedence.
Precedence is the order in which a program performs the operations in a formula. If one operator has precedence over another operator, it is evaluated first.
Higher precedence operators “bind tighter” than lower precedence operators; thus, higher precedence operators are evaluated first. Table B.1 lists the C++ operators by precedence.
