Code.org AP CSP Vocab Unit 7 - Parameters, Return, and Libraries

Parameter

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

Argument

The value passed to the parameter

Return

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

Procedural abstraction

Allows a procedure to be used only knowing what it does, not how it does it. Allows a solution to a large problem to be based on the solution of smaller subproblems. This is accomplished by creating functions (procedures) to solve each of the subproblems

Library

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

Application Programming Interface (API)

Specifications for how functions in a library behave and can be used
