This table lists the C and C++ language operators in order of precedence and shows the direction of associativity for each operator. Operators that exist only in C++ are shown in red. Operators that appear in the same group have the same precedence.

Operator precedence determines which operator will be performed first in a group of operators with different precedences. For instance 5 + 3 * 2 is calculated as 5 + (3 * 2), giving 11, and not as (5 + 3) * 2, giving 16.

The operator associativity rules define the order in which adjacent operators with the same precedence level are evaluated. For instance the expression 8 - 3 - 2 is calculated as (8 - 3) - 2, giving 3, and and not as 8 - (3 - 2), giving 7. In this case we say that subtraction is left associative meaning that the left most subtraction must be done first.
