What will be the value of x after the following code is executed? int x = 10; do { x *= 20; } while (x < 5); A. 10 B. 200 C.
dezoksy [38]

Answer:

Option B is the correct answer.

Explanation:

  • In the above code, the loop will execute only one time because the loop condition is false and it is the Do-While loop and the property of the Do-while loop is to execute on a single time if the loop condition is false.
  • Then the statement "x*=20;" will execute one and gives the result 200 for x variable because this statement means "x=x*20".
  • SO the 200 is the answer for the X variable which is described above and it is stated from option B. Hence it is the correct option while the other is not because--
  1. Option A states that the value is 10 but the value is 200.
  2. Option C states that this is an infinite loop but the loop is executed one time.
  3. Option D states that the loop will not be executed but the loop is executed one time
