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 pesm of type double, initialized to 71. Then, until pesm is less than rotro, decrement pesm.

Solution

for (double pesm = 71; pesm <= rotro; pesm--) {
    ...
}

Something to double-check in your solution:


Part 2

Translate the following while loop into a for loop:

double pe = ge;
while (pe <= risgi) {
    pe++;
    fratri(pe, 13);
}

Solution

for (double pe = ge; pe <= risgi; pe++) {
    fratri(pe, 13);
}

Part 3

Consider the following code:

A
while (B) {
    C
    D
    if (E) {
        F
        break;
    }
    G
}
H
I
J
  1. Assume the loop ends because the test condition of the loop is false on iteration 2. Write out the the order in which the statements will execute.

  2. Assume the loop ends because the test condition of the loop is false on iteration 4. Write out the the order in which the statements will execute.

Solution

  1. Order:

    A B C D E F G B C D G H I J
  2. Order:

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