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.

Example

 int* p; if (p == NULL  or  *p == 0)   skip(  );
