Question

Follow the steps of the algorithm below and identify the value of the variable x at the end. Note: The algorithm on the test will be similar but not identical.

The variable x starts with the value 1.
The variable y starts with the value 5.
Add 5 to x.
Add 5 to y.
Subtract x from y and store the result in x.
A) 5

B) 10

C) 15

D) 20

Answer 1

After following the steps of the algorithm provided, the value of the variable x is found to be 4, which does not match any of the given options A) 5 B) 10 C) 15 D) 20.

Step-by-step explanation:

To find the value of the variable x at the end of the given algorithm, we'll follow the steps in order:

1. x starts with 1.
2. y starts with 5.
3. Add 5 to x, so x becomes 1 + 5 = 6.
4. Add 5 to y, so y becomes 5 + 5 = 10.
5. Subtract x from y and store the result in x, so x becomes 10 - 6 = 4.

Therefore, the value of x at the end is 4, which is not listed in the provided options A) 5 B) 10 C) 15 D) 20. There might be an error in the provided options.
