Multiple Choice Question
Question 9
For Question 9, read the following C++ code, where all variables are integers. Which statement is correct ( )?
A. b cannot be 0, as a % b will cause an error
B. a must be less than b, otherwise a % b will cause an error
C. Both a and b must be positive integers, otherwise a % b will cause an error
D. If a is input as 0, regardless of the input value of b, the output value’s absolute value is always abs(b)
Answer: D
START OF SPRING
Solution:This question tests the greatest common divisor.
Option A: b can be 0, but the while loop will not execute.
Option B: There is no necessary size relationship between a and b.
Option C: b can be 0.
Option D: This option is correct. If a is 0 and b is 0, printing the value of a will definitely be the same as the absolute value of b. If a is 0 and b is not 0, the while loop executes once, assigning the value of b to a. Therefore, all printed values’ absolute values will be the same as the absolute value of b.
