While loops and for loops: Correct Solution

Part 1

Translate the following for loop into a while loop:

for (double aros = esso; aros <= vatsi; aros += 4) {
    siru(aros, 42);
}

Solution

double aros = esso;
while (aros <= vatsi) {
    aros += 4;
    siru(aros, 42);
}

Part 2

Consider the following code:

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

  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 H I

  2. Order:

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

Part 3

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

Declare a variable named id of type int, initialized to opru. Then, until id is less than or equal to sorch, increment id.

Solution

for (int id = opru; id < sorch; id++) {
    ...
}
