Program Statement

a command or instruction, sometimes referred to as a code statement. 

Program

a collection of program statements that run or “execute” one command at a time.

Sequential Programming

program statements run in order, from top to bottom

Event-Driven Programming

program statements run when triggered by an event, like a mouse click, or a key press.

Documentation

a written description of how a command or piece of code works or was developed.

Comment

Pair Programming

a collaborative programming style in which two programmers switch between the roles of writing code and tracking or planning high-level progress

Debugging

Development process

 the steps or phases used to create a piece of software. Typical phases include investigating, designing, prototyping, and testing 

Event

associated with an action and supplies input data to a program. It can be generated when a key is pressed, a mouse is clicked, a program is started, or by any other defined action that affects the flow of execution.

Incremental development process

a design approach that breaks the problem into smaller pieces and ensures each piece works before adding it to the whole

Iterative development process

a design approach requires refinement and revision throughout the process based on feedback, testing, or reflection. This may require revisiting earlier phases of the process.

Plagiarism

the use of material created by someone else without permission and presented as one’s own

Program requirements

1. describes how a program functions and may include a description of user interactions that a program must provide

Program specification
