CSA Vocab 2.1-2.3

Sequencing

Code going in order to make sure the right output comes from the algorithm. Building blocks of algorithms.

Selec

If and IF-ELSE statements are examples of this and it’s when a decision is being made depending on a condition. Building blocks of algorithms.

Repetition

Also known as iteration when something repeats and loops are an example. Building blocks of algorithms.

Loop

Also known as iteration and allows an algorithm to repeat certain actions until a specified condition is met.

Pseudocode

A simplified, informal way of describing the steps in an algorithm in  a language like English well following the sequence, selection, and repetition structure of programming languages.

Flowcharts

Diagram that represent steps in an algorithm

Relational Operators

< Less Than > Greater Than <= Less than or equal to >= Greater than or equal to == Equals != Does not equal

Boolean

Have true or false values

If Statement

A way to choose between different paths in an algorithm is a type of selection statement and affects low control by executing different parts of code depending on the value of the boolean expression. Can be followed by ELSE to change the one way statement to a two way statement.

Body

Segment of code to run if the IF statement is true
