F
G

  1. Assume the body of the loop executes 0 times. Write out the the order in which the statements will execute.

  2. Assume the body of the loop executes 2 times. Write out the the order in which the statements will execute.

Solution

  1. Order:

    A B F G

  2. Order:

    A B C D E C D E F G

Part 2

Translate the following natural language description of a loop into a for loop:
