Collections are composites of other objects that include data and have logical functionality to support the containers operations.
Construct
A logical control such as a selection or iteration.
Container
Containers are very data specific in the simplest forms such as an array and do not inherently have a lot of logical functionality.
Enumeration
Sequencing steps with an identifier such as a number (ex: 1. 2. 3. ...) or letter (ex: A. B. C. ...).
Used primarily in pseudocode to identify the execution sequence of statements.
Indentation
A fixed number of blank spaces to the right (ex: using the TAB key) used for aligning grouped logic that is nested.
Iteration
A construct that enables looping in a program - the ability to repeat a statement(s) easily.
Jump Statements
A poor logic flow that directs the next step of execution be an arbitrary location outside of the immediate vicinity of the current statement (ex: go to step #152). Instead, logic should be controlled using logical constructs such as selection and iteration.
Modularity
A term used for breaking down logic into various degrees of detail. This can be at a directory-level, file-level, function-level, or statement-level.
Nest
Content (statement(s), selection, or iteration) residing within a preceding construct such as a selection or iteration.
The nested content would be dependant on a preceding construct and in the case of pseudocode would be indented under it.
Obfuscate
To purposely confuse and misdirect meaning usually by way of applying meaningless names to variables and functions.
Selection
A construct that enables decisions in a program to adapt to changing conditions and execute different logic flows.
Semantic
Is another word for logic. It is the logical definition and meaning of an algorithm.
Statement
A single line of instruction (step) such as a calculation, action to display or receive user input.
Variable
A named placeholder used to reference a value. These are used for storing data for later use and evaluation.
