AP CSP Unit 7: Parameters, Returns, and Libraries

What is a benefit of using a library in a program?

• simplification

• increases time

• removes testing

• reduces abstractions

Parameter

• the value passed to the parameter

• used to return the flow of control to the point where the procedure (also known as a function) was called and to return the value of expression.

• Extracting shared features to generalize functionality

• a variable in a function definition. Used as a placeholder for values that will be passed through the function.

Argument

• The subdivision of a computer program into separate subprograms

• the value passed to the parameter

• a variable in a function definition. Used as a placeholder for values that will be passed through the function.

Return

• Extracting shared features to generalize functionality

• a group of functions (procedures) that may be used in creating new programs

• The subdivision of a computer program into separate subprograms

• used to return the flow of control to the point where the procedure (also known as a function) was called and to return the value of expression.

Procedural abstraction

• a group of functions (procedures) that may be used in creating new programs

• Extracting shared features to generalize functionality

• The subdivision of a computer program into separate subprograms

• Application Program Interface - specifications for how functions in a library behave and can be used

What is another word for a function?

• function

• command

• abstraction

• to call

If I want to make a function I must add parameters.

• True

• False

How many parameters can I add to a function.

• 1

• 2

• 3

• as many as you would like

Parameters are different than arguments

• True

• False

What will print to the console after running this code segment?

• 15

• 16

• 21

• 18
