Logical Operators
More complicated logical expressions can be built from
simpler ones by using the logical
operators: and, or, and
not . The ! operator is unary, while && and II | are binary.

The logical operators produce either 0 or 1 as their result.
Often, the operands will have values of 0 or 1, but this isn't a requirement;
the logical operators treat any nonzero operand as a true value and any zero
operand as a false value.
