Unit 2 and 3 Vocab Codio

AP CSP

pair programming

A common model of programming that facilitates collaboration

program

A collection of program students that performs a specific task when run by a computer. A program is often referred top as software.

code segment

A collection of program statements that are part of a program.

behavior of a program

How a program functions during execution and it is often described by how a user interacts with it.

event

Associated with an action and supplies input data to a program.

program documentation

A written description of a function of a code segment, event, procedure, or program and how it was developed.

comments

A form of program documentation written into he program to be read by people and does not affect how a program runs.

iterative development process

a development process that requires refinement and revision based on feedback, testing, or reflection throughout the process

incremental development process

a development process that breaks the problem into smaller pieces and makes sure each piece works before adding it to the whole

program inputs

data sent to a computer for processing by a program

program outputs

any data sent from a program to a device

variable

an abstraction inside a program that can hold a value

conditional statements or if-statements

code statements that affect the sequential flow of control by executing different statements based on the value of a Boolean expression

Boolean value

either true or false

nested conditional statements

consist of conditional statements within conditional statements

iteration statements

code statements that change the sequential flow of control by repeating a set of statements zero or more times, until a stopping condition is met

procedure

a named group of programming instructions that may have parameters and return values

parameters

input variables of a procedure

arguments

specify the values of the parameters when a procedure is called

bit

shorthand for binary digit, either 0 or 1

byte

8 bits

number bases

used to represent data, includes binary and decimal

binary (base 2)

uses only combinations of the digits zero and one

decimal (base 10)

uses only combinations of the digits 0-9

modulus operator

arithmetic operator used to return the remainder of a division operation

overflow error

an error caused by the limitation of the range of values and mathematical operations on those values by representing integers with a fixed number of bits

round-off error

an error caused by the limitation of using a fixed number of bits to represent real numbers which limits the range and mathematical operations on those values

list

an ordered sequence of elements

index

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

complete list traversal

all elements in the list are accessed

partial list traversal

only a portion of elements in the list are accessed
