The stream that is used for output to the screen is called ___________.

Loops are used when we need our program to make a choice between two or more things.

The integer 0 is considered true.

Given the following code fragment and the input value of 2.0, 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; }

Which of the following lines correctly reads a value from the keyboard and stores it in the variable named myFloat?

The braces for a loop define the ____________ of the loop.

Is << used for input or output? ____________

What is the correct conditional statement to determine if x is between 19 and 99? __________________

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

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

<< is called the stream ____________________ operator.

What is the value of x after the following statements? Int x; X = 15 %4;

The body of a do-while loop always executes at least once.

>> is known as the stream ____________ operator.

It is legal to declare more than one variable in a single statement.

Given the following code fragment, what is the final value of y? Int x, y; X = -1; Y = 0; Whilex < 3) { Y += 2; X += 1; }

The opposite of less than is greater than
