pair programming

pair programming

a common model of programming that facilitates collaboration

program

a collection of program statements that performs a specific task when run by a computer. Often referred to 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; 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 the function of a code segment, event, procedure, or program and how it was developed

comments

a form of program documentation written into the program to be read by people and do 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. Input can come in a variety of forms, such as tactile, audio, visual, or text

variable

an abstraction inside a program that can hold a value; each one has associated data storage that represents ONE value at a time, but that value can be a list or other collection that in turn contains multiple values

conditional statements (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

program outputs

any data sent from a program to a device; can come in a variety of forms, such as tactile, audio, visual, or text
