Among the above three logical operators, logical NOT! has the highest priority, logical AND && followed by , logical OR || has the lowest priority . That is, the priority order of arithmetic, logical, and assignment operators is:

logical NOT! >arithmetic> logical AND&&, logical OR|| > assignment=

The value of a logical expression is a logical value, that is, Boolean type (bool). This type is new in C99. Some compilers may not support this type yet.

Logical values ​​are divided into logical true values ​​and logical false values. Under normal circumstances, during judgment, only zero values ​​are judged as logical false values ​​(false), and all non-zero values ​​can be judged as logical true values ​​(true); when storing and representing, usually, 1 is used to represent logical values. True value, 0 represents a logical false value.

The operation rules of logical AND && operator: The result is true only when both operands are logically true. In all other cases, the result is false.

The operation rules of logical OR || operator: The result is false only when both operands are logically false. In all other cases, the result is true.
