or operator — Logical or operator
logical-or-expr := logical-or-expr "||" logical-and-expr |
logical-or-expr or logical-and-expr
The logical or operator converts its
operands to type bool and returns a
bool result. This built-in operator
is a short-circuit operator, so if the left operand is true, the expression yields true without evaluating the right operand.
Note that if operator or is overloaded, it cannot be
short-circuited and must evaluate both operands.
The keyword or is
interchangeable with the ||
token.
