Programming Logic and Design, 5th edition. Ch 5-8

1. What is a repetition structure?

• causes a statement or set of statements to execute repeatedly.

• Writing a long sequence of statements can be time consuming

• uses a true/false condition to control the number of times that it repeats.

What is an off-by-one error?

• The series of values separated with commas

• Because array subscripts start at 0 rather than 1, you have to be careful not to perform.

• they do not allow a program to use an invalid array subscript

• a loop iterates one time too many or one time too few.

This is a prewritten function that is built into a programming language.

• standard function

• library function

• custom function

• cafeteria function

Which type of loop repeats a statement or set of statements as long as the Boolean expression is false?

• For

• Do-Until

• Do-While

• While

The test condition in a While loop must always be an integer value.

• True

• False

Modules can be called from statements in the body of any loop.

• True

• False

How many times would the following loop iterate?

Set k = 1

Do

Display k

Set k = k + 1

Until k > 2

• 2

• infinite

• 1

• 3

1. Can you store a mixture of data types in an array?

• False

• True

How many times would the following loop iterate?

Set k = 1

While k <= 5

Display k

End While

• 0

• 4

• 5

• infinite

1. What is usually the first subscript in an array?

• ( - )

• 0

• 1

• ( _ )
