Chapter 5 135
Operator Precedence
Precedence is the order in which the compiler groups operands with operators. The C
compiler evaluates certain operators and their operands before others. If operands are not
grouped using parentheses, the compiler groups them according to its own rules.
The following lists C operator precedence in highest to lowest precedence:
