While loops and for loops: Correct Solution

Part 1

Consider the following code:

A
while (B) {
    C
    D
    if (E) {
        F
        break;
    }
    G
}
H
I

  1. Assume the loop ends because the test condition of the loop is false on iteration 2. 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 E F G B C D G H I

  2. Order:

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

Part 2

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

Declare a variable named oa of type int, initialized to ia. Then, until oa is less than or equal to ost, divide oa by 3.

Solution

for (int oa = ia; oa < ost; oa /= 3) {
    ...
}

Something to double-check in your solution:

Part 3

Translate the following while loop into a for loop:

short ne = emun;
while (ne <= eou) {
    ne -= 3;
    haiDimiol(ne);
}

Solution

for (short ne = emun; ne <= eou; ne -= 3) {
    haiDimiol(ne);
}
