   Answer questions 4 and 5 for the pseudocode below:

   For (index = 1, index < 14, index = index + 3)
       print index
   endFor
   

4. How many times will the "print index" statement be executed:

   5
   4
   6
   3
   

5. What will be the value of index for the second iteration:

   5
   4
   6
   3
   

6. One wants to print even numbers between 14 and 20. Which for loop will accomplish this:

   For (i = 12, i < 20, i = i + 2)
   For (i = 14, i < 20, i = i + 2)
   For (i = 14, i <= 20, i = i + 2)
   For (i = 14, i < 23, i = i + 2)
   

7. What will be printed for the following code?

   product = 1
   For (i = 1, i <=3, i = i + 1
       product = product * i
   endFor

9. Is there anything wrong with the loop shown below assuming sales to be 10000:

   While (sales > 0)
       print sales
   endWhile
   

   Nothing is wrong
   Loop will run forever
   

10. What will be printed for the code shown below:

    sum = 0
    For (i = 1, i <= 4, i = i + 1)
