what are the out come for these C++ programming problems?

1. What value is assigned to fee by the if statement when speed is 8?

if (speed < 35)

fee = 10;

else if (speed < 25)

fee = 30;

else if (speed <10)

fee = 50;

2. What does the following statement print if i has the value 20? What does it print if i has the value -20?

cout << i >= 0 ? i : -i << endl;

3. What output does the following program fragment produce?

int i = 1;

while (i <= 128)

{

cout << i << “\t”;

i *= 3;

}

4. What output does the following program fragment produce?

int y, x = 1, total = 0;

while (x < 10)

{

y =x + x;

cout << y << endl;

total += y;

++x;

}

cout << “Total is ”<< total << endl;
