Question
Question 1 int n1 = 12; int n2 = 18; int n3 = 21; What is the result of each boolean expression? n1 < n2
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)
cout << "true" << endl;
else
cout << "false" << endl;
true
false
Question 4
What is the output of the following code if score has a value of 85?
if (score < 60)
cout << "F" << endl;
else if (score < 70)
cout << "D" << endl;
else if (score < 80)
cout << "C" << endl;
else if (score < 90)
cout << "B" << endl;
else
cout << "A" << endl;
