Explanatory Question

Analyse the following program segment and determine how many times the loop will be executed and what will be the output of the program segment: 

int p = 200;

while(true)
{
    if(p < 100)
        break;
    p = p - 20;
}

Answer with Explanation

Analysis of the loop:

Initial value of p = 200. The loop keeps subtracting 20 from p until p < 100. The loop executes as follows:

  • 1st iteration: p = 200 - 20 = 180
  • 2nd iteration: p = 180 - 20 = 160
  • 3rd iteration: p = 160 - 20 = 140
  • 4th iteration: p = 140 - 20 = 120
  • 5th iteration: p = 120 - 20 = 100
  • 6th iteration: p = 100 - 20 = 80

The loop stops when p becomes 80. The output will be:

Output:
80

The loop will be executed 6 times.
