A.7.14 Logical AND Operator

  • logical-AND-expression:
    • inclusive-OR-expression

      logical-AND-expression && inclusive-OR-expression

The && operator groups left-to-right. It returns 1 if both its operands compare unequal to zero, 0 otherwise. Unlike &, && guarantees left-to-right evaluation: the first operand is evaluated, including all side effects; if it is equal to 0, the value of the expression is 0. Otherwise, the right operand is evaluated, and if it is equal to 0, the expression's value is 0, otherwise 1.

The operands need not have the same type, but each must have arithmetic type or be a pointer. The result is int.
