What made you want to look up short-circuit ? Please tell us where you read or heard it (including the quote, if possible).
The And Operator performs logical conjunction on two Boolean expressions. If both expressions evaluate to True , then And returns True . If at least one of the expressions evaluates to False , then And returns False .
In simple terms, a short circuit gives electricity the path of least resistance between two conductive points. Less distance between the two points means less resistance, which means your short circuit will produce more heat and result in burns and fires.
The conditional-AND operator cannot be overloaded, but overloads of the regular logical operators and operators true and false are, with certain restrictions, also considered overloads of the conditional logical operators.
