Answer to Question 10A-2

Here is the loop for reference. 

  int r = 2;
  int n = 1;
  while(n < 10)
  {
    if(n % 2 == 0)
    {
      n = n + 1;
      r = r * r;
    }
  }

 n     r 
1   2
2   2
3   4
4   4
5   16
6   16
7   32
8   32
9   64
10   64

The last line shows the values of n and r when the top of the loop is reached but the loop is finished.
