While loops and for loops: Correct Solution


Part 1

Consider the following code:

A
B
C
while (D) {
    E
    F
}
G
H
I
  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 2 times. Write out the the order in which the statements will execute.

Solution

  1. Order:

    A B C G H I
  2. Order:

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

Part 2

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

Declare a variable named pena of type int, initialized to me. Then, until pena is greater than osAic, multiply pena by 4.

Solution

    ...
}
