Chapter 4 (Decision Structures and Boolean Logic)

A _____ structure can execute a set of statements only under certain circumstances.

A _____ structure provides one alternative path of execution. If the condition that is being tested is true, the program takes the alternative path.

In pseudocode, the "If-Then" statement is an example of a _____.

A _____ expression has a value of either true or false.

The symbols >, <, and == are all _____ operators.

A _____ structure tests a condition and then takes one path if the condition is true, or another path if the condition is false.

You use an _____ statement in pseudocode to write a single alternative decision structure.

You use an _____ statement in pseudocode to write a dual alternative decision structure.

A _____ structure allows you to test the value of a variable or an expression and then use that value to determine which statement or set of statements to execute.

A _____ section of a "Select Case" statement is branched to if none of the case values match the expression listed after the "Select" statement.

AND, OR, and NOT are _____ operators. They are used to create complex Boolean expressions.

A compound Boolean expression created with the _____ operator is true only if both of its subexpressions are true.

A compound Boolean expression created with the _____ operator is true if either of its subexpressions is true.

The _____ operator takes a Boolean expression as its operand and reverses its logical value.

A _____ is a Boolean variable that signals when some condition exists in the program.

When the "If-Then" statement executes, the _____ is tested. If it is true, the statements that appear between the "If" clause and the "End If" clause are executed.

A logical design that controls the order in which a set of statements executes is a _____.

To test more than one condition, a decision structure can be _____ inside another decision structure.

The _____ lets the value of a variable or an expression determine which path of execution the program will take.

The case structure is a _____.

What does the case structure test, in order to determine which set of statements to execute?

You need to write a multiple alternative decision structure, but the language you are using will not allow you to perform the test you need in a "Select Case" statement. What can you do to achieve the same results?

If an expression on the left side of an AND operator is false, the expression on the right side will not be checked. This is an example of _____.

What is a compound Boolean expression?

If an expression on the left side of an OR operator is true, the expression on the right side will not be checked. This is an example of _____.
