Question

Which of the following is the correct if clause to determine whether y is in the range 10 through 50, inclusive?

a. if 10 < y or y > 50:
b. if 10 > y and y < 50:
c. if y >= 10 and y <= 50:
d. if y >= 10 or y <= 50:

Answer 1

The correct if clause for determining if y is within the inclusive range of 10 through 50 is 'c. if y >= 10 and y <= 50:'. This ensures y is checked to be both greater than or equal to 10 and less than or equal to 50.

Step-by-step explanation:

The correct if clause to determine whether y is in the range of 10 through 50, inclusive, is c. if y >= 10 and y <= 50:. This expression checks if y is greater than or equal to 10 and less than or equal to 50, which is the correct way to include the endpoints of the range in the condition.

Options a and d use the or logical operator, which would incorrectly allow values outside of the specified range. Option b uses the and logical operator but has the inequality signs pointing in the wrong directions, excluding values within the specified range.
