Unit 6/7 - Lists, Loops, and Traversals / Parameters, Return, and Libraries

Question 1

List

Answer 1

an ordered collection of elements

Question 2

Element

Answer 2

an individual value in a list that is assigned a unique index

Question 3

Index

Answer 3

a common method for referencing the elements in a list or string using numbers

Question 4

Iteration

Answer 4

a repetitive portion of an algorithm which repeats a specified number of times or until a given condition is met.

Question 5

Infinite Loop

Answer 5

occurs when the ending condition will never evaluate to true.

Question 6

Traversal

Answer 6

the process of accessing each item in a list one at a time.

Question 7

Data Abstraction

Answer 7

manage complexity in programs by giving a collection of data a name without referencing the specific details of the representation.

Question 8

Parameter

Answer 8

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

Question 9

Argument

Answer 9

the value passed to the parameter

Question 10

Return

Answer 10

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.

Question 11

Procedural Abstraction

Answer 11

a process and 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.)

Question 12

Library

Answer 12

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

Question 13

API

Answer 13

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

Question 14

Modularity

Answer 14

the subdivision of a computer program into separate subprograms
