- comments
- code written for the benefit of programmers and never seen by end-users;
- a line of code, starting with a percentage sign and a blank space (% ), which is ignored by the computer;
- comments appear in the IDE editor in green
- concatenation
- the joining in sequence of character strings
- end-user
- person who uses a program to accomplish a task like write a document, edit an image, play a game, or communicate over a network;
- during application development, students are both programmers and end-users, so it is important that students remember which role they are playing
- executable
- the binary-code version of a program which can be executed directly by a computer without translation; Windows executable files have the extension .exe; OS X executable files have the extension .app

- operator
- a symbol or keyword which represents an operation to be performed on one or more operands;
- unary operators operate on a single operand;
- binary operators operate on a two operands
- programmer
- a person who designs algorithms, writes and tests source code, and produces an executable
- source code
- the plain-text version of a program which can be read by humans; this version cannot be executed directly by the computer; end-users almost never see this code; exception: open-source programs; Turing source-code files have the extension .t
- statements
