Question

Identify the false statement.

a. You can improve loop performance by making sure the loop does not include unnecessary operations in the body of the loop.
b. You can improve the performance of a loop by making sure the loop does not include unnecessary operations in the tested expression.
c. You can improve loop performance when two conditions must both be true by testing for the most likely occurrence first.

Answer 1

In the context of optimizing loop performance in programming, the first two statements regarding avoiding unnecessary operations in the loop body and the tested expression are true. The last statement about testing conditions is potentially false if misunderstood, but it embraces the concept of short-circuit evaluation when applied correctly.

Step-by-step explanation:

The subject of this question relates to optimizing loop performance in computer programming. When reviewing the statements, here are the evaluations:

• You can improve loop performance by making sure the loop does not include unnecessary operations in the body of the loop. True.
• You can improve the performance of a loop by making sure the loop does not include unnecessary operations in the tested expression. True.
• You can improve loop performance when two conditions must both be true by testing for the most likely occurrence first. This statement is misleading and can be considered false depending on interpretation. The reason is that if both conditions are necessary for the loop to execute, the order may not improve the performance much. However, if the intent is to say that short-circuit evaluation can be used where the most likely to be false condition is tested first for the possibility to skip the second condition check, then it could be considered true.
