Question

If we wanted to write an if-statement that executes whenever the real number x is between 10.0 and 20.0,how should the test condition be written? A)10.0 < x || x > 20.0 B)10.0 < x && x > 20.0 C)10.0 < x && x < 20.0 D)10.0 < x || x < 20.0

Quizplus · Accepted Answer

The test condition should check both that x is greater than 10.0 and less than 20.0, hence we need to use the logical operator &&. Therefore, the correct test condition is 10.0 < x && x < 20.0. Choice A and D are incorrect because they use the logical operator || which means "or", whereas we need to use "and" in this situation. Choice B is incorrect because it incorrectly claims that the number must be greater than 10.0 and less than 20.0 at the same time, which is impossible.
