Unit 3 Test

In programming, what is iteration?

• The repetition of steps within a program

• The order in which instructions are carried out

• A decision point in a program

Why is iteration important?

• It determines the order in which instructions are carried out

• It allows code to be simplified by removing duplicated steps

• It allows multiple paths through a program

What is iteration known as?

• Looping

• Crashing

• Repeating

holds the value of information that may change in a computer program

• conditional

• iteration

• variable

has only two values: true or false

• boolean variable

• string variable

• sprite

Which of the following is a true statement about program documentation?

• Program documentation should not be changed after it is first written

• Program documentation is only needed for programs in development; it is not needed after a program is completed.

• Program documentation is useful when programmers collaborate but not when a programmer works individually on a project.

• Program documentation is useful during initial program development and also when modifications are made to existing programs.
