Input

data given to a computer for processing by a program. Can come in a variety of forms, such as tactile interaction, audio, visuals, or text.

output

any data that you receive from the computer. Can come in a variety of forms, such as tactile interaction, audio, visuals, or text.

Algorithm

a sequence of instructions

User Interface (UI)

the components that allow a user to interact with a piece of software. User interfaces can include a variety of forms such as buttons, menus, images, text, and graphics.

User Friendly

easy to use and visually aplealing

Good UI

A good UI has very straight forward buttons and performs how they are meant to.  - clarity - consistency - responsiveness 

Bad UI

very unorganized and does not work properly. 

Ambiguous

not specific

Why is it important to have unambigous coding

so you know which parts of the code does what and makes it easier to fix

Program

 a sequence of instructions that tells the computer what to do.

comment

a note in a program for humans

Event driven programming

runs when triggered by an event, like a mouse click or a key press

• Programs run differently each time depending on user interactions

Sequential Programing

program statements run in order, from top to bottom.

• No user interaction

• Code runs the same way every time

Debugging

fixing problems in a program

Assignment

=, set

Comparison

==, !=, <, <=, >, >=

asking a yes or no question

string

A word or sentence, a sequence of characters

In quotations

variable

usually has var before it and no quotes

number

a number with no quotes

global variable

Accessible in throughout the entire program

local variable

only works in a function or when its defines

boolean

A true or false value

Condition

a way to decide to execute code or not

how computers make decisions using conditionals.

they run the if statements

a condition always evaluates to a value of

true or false

MOD operator

a divison sign to be if the outcome is odd than it runs one code and if it’s even than it’ll run another code. the user puts in the numbers.

==

equality

!=

inequality

>

greater than

>=

greater than or equal

<

less than

<=

less than or equal

function

when you make a thing in code and you can just call it when you need it so you don’t have to rewrite it again.

AND

&& requires both to be true 

OR

|| if either are true then true

NOT

! does the opposite 

diffence between = and ==

coco = 1 coco is 1

coco == 1 coco is equal to 1

expresion

a combination of operators and values that evaluate to a single value

Assignment Operator

allows a program to change the value represented by a variable
