      int [] sample=new int[8];
      int i, k;

      Using the declarations above, show the array after the following statements:

      for (k=0; k<8; k++)
         if (k % 2 == 0)
            sample[k] = k;
         else
            sample[k] = k + 100;

      Write the statements to add up those elements of an array of ints (of
      size 25) which have an even subscript.

      Write the statements to add up those elements of an array of ints (of
      size 25) which have an even value.

      What will the following program segment print?

      int nums = new int[10];
      int i;
      for (i = 9 ; i >= 0 ; i--) {
         nums[i] = 5 * (i + 1);
         System.out.print(nums[i] + "  ");
      }
      System.out.println();
      for (i = 0 ; i < 10 ; i++)
         System.out.print(nums[i] + "  ");
      System.out.println();
      for (i = 8 ; i >= 0 ; i--)
         nums[i+1] = nums[i];
      for (i = 0 ; i < 10 ; i++)
         System.out.print(nums[i] + "   ");
      System.out.println();
