Final answer:
The assertion that short-circuit evaluation is only relevant for expressions with relational operators is false. It applies to logical expressions generally, especially those using Boolean operators like AND, OR, and NOT, to optimize the evaluation process.
Step-by-step explanation:
The statement that the short-circuit method of evaluating logical expressions is only relevant to those expressions that make use of at least one relational operator is false. The short-circuit evaluation is a technique used to evaluate compound logical expressions, typically involving Boolean operators such as AND, OR, and NOT, and not exclusively relational operators.
In short-circuit evaluation, the result is determined without evaluating all operands and operators. For example, in a logical AND expression, if the first operand evaluates to false, the overall expression can never be true, so the remaining operands are not evaluated. Similarly, in a logical OR expression, if the first operand evaluates to true, the overall expression will be true regardless of the other operands, so they are not evaluated either.
Boolean operators are fundamental to logical expressions and using them with short-circuit evaluation can optimize the evaluation process by avoiding unnecessary operations.
