While loops and for loops: Correct Solution

Part 1

Translate the following while loop into a for loop:

double ca = 0;
while (ca <= niic) {
    ca -= 4;
    pelDuszep();
    iangei(ca, 33);
}

Solution

for (double ca = 0; ca <= niic; ca -= 4) {
    iangei(ca, 33);
    pelDuszep();
}

Part 2

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

Declare a variable named ac of type int, initialized to 13. Then, until ac is less than cabel, decrement ac.

Solution

for (int ac = 13; ac <= cabel; ac--) {
    ...
}

Something to double-check in your solution:

Part 3

Consider the following code:

A
B
C
for (D; E; F) {
    G
    H
}
I
J

  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 D F I J

  2. Order:

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