Cutting a big program up into smaller subprograms (functions, procedures, etc)

• modularity

• procedural abstraction

In computer programming, this allows you to use a function knowing WHAT it does but not necessarily HOW it does it.

Directions for how a collection of functions behave and can be used

• Library

• API

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

• the orange x is a parameter

• the orange x is an argument

• the "7" is a parameter

• the "7" is an argument

• the variable "y" on line 2 is a parameter

• the variable "y" on line 2 is an argument

• the variable "year" in function getYear(year)

  is a parameter

• the variable "year" in function getYear(year)

  is an argument

a variable used as a place holder for a value passed to a function
