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 teic of type int, initialized to 2. Then, until teic is less than or equal to oss, increment teic.

Solution

for (int teic = 2; teic < oss; teic++) {
    ...
}

Something to double-check in your solution:

• Note that the problem says “until,” not “while.” Did you use the correct operator in the loop’s end condition (teic < oss)?

Part 2

Consider the following code:

A
B
while (C) {
    D
    E
}
F
G
H

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 3 times. Write out the the order in which the statements will execute.

Solution

1. Order:

   A B F G H

2. Order:

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