Which expression evaluates to 14 if integer y = 13?
A.
11 + y % 5
B.
11 - y / 5.0
C.
(11 + y) % 5
D.
11.0 - y / 5
The Answer Is:
A
This question includes an explanation.
Explanation:
To find an expression that evaluates to 14 when y = 13, let’s evaluate each option:
A. 11 + y % 5: The modulo operation (%) gives the remainder after division. For y = 13, 13 % 5 equals 3. Adding 11 to 3 results in 14, so this expression is correct.
B. 11 - y / 5.0: Dividing 13 by 5.0 gives 2.6. Subtracting 2.6 from 11 does not yield 14, so this expression is incorrect.
C. (11 + y) % 5: Adding 11 to 13 results in 24. Taking the modulo of 24 with 5 gives 4, which is not equal to 14. Therefore, this expression is incorrect.
D. 11.0 - y / 5: Dividing 13 by 5 gives 2.6. Subtracting 2.6 from 11.0 does not yield 14, so this expression is incorrect.
The correct expression is A. 11 + y % 5.
