CS Chapter 3

When a program compares characters, it actually compares the __________ codes

ASCII

A(n) __________ expression has a value of either true or false.

Boolean

T/F A compound Boolean expression created with the or operator is true only when one subexpression is true.

F

T/F A program can be made of only one type of control structure. You cannot combine structures.

F

T/F A single alternative decision structure tests a condition and then takes one path if the condition is true, or another path if the condition is false.

F

T/F It is best to use the or operator when determining whether a number is inside a range.

F

T/F You can write any program using only sequence structures.

F

T/F A compound Boolean expression created with the and operator is true only when both subexpressions are true.

T

T/F A decision structure can be nested inside another decision structure.

T

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

and

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

decision

A(n) _________ structure tests a condition and then takes one path if the condition is true, or another path if the condition is false.

dual alternative decision

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

flag

Boolean variables are commonly used as ___________ and if it is set to ___________, it indicates the condition does not exist.

flags, False

You can use an ____________ statement to write a single alternative decision structure.

if

The __________ statement causes one or more statements to execute only when a Boolean expression is __________.

if, true

You use a(n) __________ statement to write a dual alternative decision structure.

if-else

and, or, and not are __________ operators.

logical operators

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

not

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

or

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

relational

A logical design that controls the order in which a set of statements execute is called a __________.

sequence structure

If the expression on the left side of the and operator is false, the expression on the right side will not be checked. This is called as __________.

short-circuit evaluation

A____________ structure provides one alternative path of execution.

single alternative decision
