Question 1

int n1 = 12;

int n2 = 18;

int n3 = 21;

What is the result of each boolean expression?

n1 < n2 ["True", "False"]

n3 == n2 ["True", "False"]

n3 == (n1 + 9) ["True", "False"]

(n2 > n1) && (n2 < n3) ["True", "False"]

n3 >= (n1 + n2) ["True", "False"]

! (n1 == n2) ["True", "False"]

Question 2

The following code will result in a divide by 0 error.

intValue = 0;

if (intValue != 0 && (10 / intValue) > 2)

// do something

True

False

Question 3

What is the output of the following code if intValue = 0?

if (intValue = 0)

else

cout << "false" << endl;

true

false

cout << "D" << endl;

else if (score < 80)

cout << "C" << endl;

else if (score < 90)

cout << "B" << endl;

else
