chapter 2

The following code will have what result? int test = 10; while (test == 10) { cout << test; }

An infinite loop

To check if a value is not equal to another value, use which relational operator?

!=

The value of 'score' will be between what range of numbers? int score = (rand() % 50) + 1;

1 and 50

The expression (5-5) evaluates to true

False

Seeding a random number generator does what?

Make sure the starting point for our number sequence is in a different spot each time

Using a switch statement allows us to do what?

Provide different code to run for different possible values of a variable

Code provided for each case in a switch statement can and should be separated by what keyword?

break

What keyword can we use to provide code that will execute if the expression in an 'if' statement evaluates to false?

else

Find the error in the following code. if (5 < 10); { std::cout << 'This is displayed'; }

There shouldn't be a semicolon after (5 < 10)

Initializing a variable used in the loop expression is necessary for a 'while' loop, but not required for a 'do' loop.

True

Switch statements can only be used with values that can be evaluated as an 'int'.

True

What will the following expression evaluate to (in boolean format)? ((5 < 5 || 5 > 3) && 5 >= 5)

True

The 'default' expression provided in a switch statement will run no matter what the value of the switch target is.

False

The rand() function will generate random numbers is a different sequence each time, whether we seed it or not.

False

To check if two values are equal, use the '=' relational operator.

False

What will the following expression evaluate to (in boolean format)? (5 < 10 && 5 < 5)

False

What will the following expression evaluate to (in boolean format)? (5 < 2 || (5 == 5 && 5 <= 3))

False

You have to place a semicolon after the closing curcly brace of an if statement.

False

In the following code, what message(s) will be displayed to the output? if (5 != 5) { std::cout << 'Message 1'; if (5 > 5) { std::cout << 'Message 2'; } } else { std::cout << 'Message 3'; }

Message 3

What will the following expression evaluate to (in boolean format)? (5 >= 10 || 5 == 5)

True

Printing our player's score to the screen is an example of what step in the 'Game loop'?

Updating the display

To stop a loop and continue at the code below the loop statements, use what keyword?

break

What is the difference between a 'while' loop and a 'do' loop?

'While' loops evaluate their expression before their statement block, 'do' loops evaluate after

In the following expression, what will the value of 'score' be at the end? int score = 10; if (5 <= 4) { score++; }

10
