While loops and for loops: Correct Solution


Part 1

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

Declare a variable named us of type int, initialized to twe. Then, until us is less than piOo, subtract 4 from us.

Solution

for (int us = twe; us <= piOo; us -= 4) {
    ...
}

Part 2

Consider the following code:

A
while (B) {
    C
    D
    if (E) {
        F
        G
        break;
    }
    H
}
I
J
K
  1. Assume the loop ends because the test condition of the loop is false on iteration 1. Write out the the order in which the statements will execute.

  2. Assume the loop ends because the test condition of the loop is false on iteration 3. Write out the the order in which the statements will execute.

Solution

  1. Order:

    A B C D H I J K
  2. Order:

    A B C D E F G H B C D E F G H B C D H I J K
