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 ent of type int, initialized to fuuc. Then, until ent is less than hiu, subtract 4 from ent.

Solution

for (int ent = fuuc; ent <= hiu; ent -= 4) {
    ...
}

Something to double-check in your solution:

• Note that the problem says “until,” not “while.” Did you use the correct operator in the loop’s end condition (ent <= hiu)?

Part 2

Consider the following code:

A
B
while (C) {
    D
    E
}
F
G

1. Assume the body of the loop executes 1 time. Write out the the order in which the statements will execute.

2. Assume the body of the loop executes 3 times. Write out the the order in which the statements will execute.

Solution

1. Order:

   A B C D E F G

2. Order:

   A B C D E C D E C D E F G
