Logical Operators

The logical operators are typically used in decision making, for instance, in an "if" statement. They can be used to selectively execute code based on the outcome of the condition. In the first example, if both x and y have non-zero values, then the result of the expression will be non-zero (TRUE - usually 1). If either or both x and y are zero, then the result is zero (FALSE).

We will see these in action in the section on decision making.

Operator Operation Example Result (FALSE=0, TRUE≠0)
&& Logical AND x && y 1 if both x≠0 and y≠0, else 0
| | Logical OR x || y 0 if both x=0and y=0, else 1
! Logical NOT !x 1 if x=0, else 0
​

In conditional expressions, any non-zero value is interpreted as TRUE. A value of 0 is always FALSE.
