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 di of type int, initialized to hess. Then, until di is greater than bla, multiply di by 3.

Solution

for (int di = hess; di >= bla; di *= 3) {
    ...
}

Part 2

Consider the following code:

A
B
while (C) {
    D
    E
    if (F) {
        G
        H
        break;
    }
    I
}
J
K
  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 3. Write out the the order in which the statements will execute.

Solution

  1. Order:

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

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