Precedence of Operators
Precedence of Operators
Operators in expressions can be arithmetic (signed, unsigned, or logical) or conditional
(Boolean or relational, signed or unsigned). Within an expression, the compiler
evaluates the operators in the order of precedence. Within each level of precedence,
the compiler evaluates the operators from left to right. Table 4-1
shows the level of
precedence for each operator, from highest (0) to lowest (9).
