Exam 2: C++ Basics

What is the correct way to write the condition y < x < z?

Each time a loop body executes is known as an _______________________.

Given the following code fragment and the input value of 4.0, what output is generated? Float tax; Float total; Cout << "enter the cost of the item\n"; Cin >> total; If total >= 3.0) { Tax = 0.10; Cout << total + total * tax) << endl; } Else { Cout << total << endl; }

Executing one or more statements one or more times is known as:

In the following code fragment, x has the value of 3. int x = 3;

What is the output of the following code fragment? Int x=0; While x < 5) Cout << x << endl; X ++; Cout << x << endl;

What is the value of x after the following statement? Float x; X = 3.0 / 4.0 + 3 + 2 )/ 5

What is the value of x after the following statements? Int x; X = x + 30;

What is the output of the following code? Float value; Value = 33.5; Cout << "value" << endl;

Every line in a program should have a comment.

What is the value of x after the following statements? Double x; X = 0; X += 3.0 * 4.0; X -= 2.0;

If x has the value of 3, y has the value of -2, and w is 10, is the following condition true or false? If x < 2 && w < y)

What is the opposite of x < 20 && x > 12)? _______________________

Given the following code fragment, and an input value of 5, what is the output? Int x; If x< 3) { Cout << "small\n"; } Else { If x < 4) { Cout << "medium\n"; } Else { If x < 6) { Cout << "large\n"; } Else { Cout << "giant\n"; } } }

if-else statements that are inside other if-else statements are said to be _______________.

Given the following code fragment, and an input value of 3, what is the output that is generated? Int x; Cout <<"Enter a value\n"; Cin >> x; Ifx=0) { Cout << "x is zero\n"; } Else { Cout << "x is not zero\n"; }

Which of the following is not a valid identifier?
