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 i of type short, initialized to 57. Then, until i is greater than rhee, multiply i by 4.

Solution

for (short i = 57; i >= rhee; i *= 4) {
    ...
}

Part 2

Consider the following code:

A
B
C
while (D) {
    E
    F
    if (G) {
        H
        break;
    }
    I
}
J
K
  1. Assume the loop breaks on iteration 2. Write out the the order in which the statements will execute.
