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 ra of type int, initialized to ioc. Then, until ra is not equal to foem, add 3 to ra.

Solution

for (int ra = ioc; ra != foem; ra += 3) {
    ...
}

Part 2

Consider the following code:

A
B
C
while (D) {
    E
    F
    if (G) {
        H
        break;
    }
    I
}
J
  1. Assume the loop breaks on iteration 1. Write out the the order in which the statements will execute.

  2. Assume the loop breaks on iteration 4. Write out the the order in which the statements will execute.

Solution

  1. Order:

    A B C D E F G J
  2. Order:

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