Question

Give the output of the following program segment and mention how many times the loop is executed.

     int K= 1;

     do

     {K+=2;

     System. out.println (K);

     } while (K<=6);

Answer 1

3
5
7

Number of times the loop is executed

The loop is executed 3 times.

• Initialisation: K starts at 1.
• 1st Iteration: K becomes 1 + 2 = 3. It prints 3. The condition (3 ≤ 6) is true, so the loop continues.
• 2nd Iteration: K becomes 3 + 2 = 5. It prints 5. The condition (5 ≤ 6 ) is true, so the loop continues.
• 3rd Iteration: K becomes 5 + 2 = 7. It prints 7. The condition (7 ≤ 6) is false, so the loop terminates.
