A set of boolean operands will only have a logical AND (&&) operator (logical conjunction) that is true if and only if all of the operands are true. If not, it will be untrue.
A logical operator is a symbol or word that joins two or more expressions in such a way that the value of the resulting compound expression solely depends on the value of the original expressions and the meaning of the operator. The AND, OR, and NOT logical operators are often used. The logical NOT (!) operator transforms truth into untruth and vice versa. Normally, boolean (logical) values are used with it. When applied to non-Boolean values, it returns true unless its sole operand can be transformed to false. The two vertical line symbols stand in for the logical OR operator.
