Unit 7 - Parameters, Return, and Libraries Unit

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 procedure (also known as a function) was called and to return the value of expression.

Procedural abstraction

a process that allows a procedure to be used only knowing what it does, not how it does it. Procedural abstraction allows a solution to a large problem to be based on the solution of smaller subproblems. This is accomplished by creating procedures to solve each of the subproblems.

Library

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

API

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

Modularity

the subdivision of a computer program into separate subprograms
