logical-and-expression && inclusive-or-expression
The && operator groups left-to-right. The operands are both
contextually converted to bool.
The result is true if both operands are true and
false otherwise. Unlike &, && guarantees
left-to-right evaluation: the second operand is not evaluated if the
first operand is false.
The result is a bool.
If the second expression is evaluated, every
value computation and
effect associated with the first expression is sequenced before every
value computation and side effect associated with the second expression.
