Algorithms

A set of instructions to do a task

Sequencing

Do a task in the order it’s specified in.

Iteration

If a certain condition is true, then a certain step can be made true

Representation

Flowcharts and pseudocode

Flowcharts for decisions.

Oval = edpoint Arrow = relationship parallelogram - input and output rectangle - process diamond - decision

Arithmetic

Different operations

• • addition
• • subtraction
• • multiplication / - division // - modulus - remainder ** - exponent use variables as well as numbers follows order of operations (PEMDAS)

Variables

ways to make variables numbers other variables result of an operation procedure call

Sequencing is important

Strings

A phrase in “quotation marks”

Subtrings

a part of a string
