Question

What is the ending value of x?

x = 0
i = 1
while i <= 6:
x += i
i += 2

Answer 1

The ending value of x is determined by running a while loop that adds the value of i, which increments by 2 in each iteration, to x until i is greater than 6. After three iterations, i becomes 7 and the loop terminates, resulting in the final value of x being 9.

Step-by-step explanation:

To determine the ending value of x, we need to examine the given while loop. The loop starts with x equal to 0 and i equal to 1. In each iteration of the loop, x is incremented by the value of i, and i is then incremented by 2. The loop runs as long as i is less than or equal to 6.

• First iteration: i = 1, x += 1 (x = 1)
• Second iteration: i = 3, x += 3 (x = 4)
• Third iteration: i = 5, x += 5 (x = 9)

After the third iteration, i is incremented by 2, which results in i being 7, and the condition i ≤ 6 is no longer true. Therefore, the loop terminates and the final value of x is 9.
