Computer Science I Unit 1!

argument

information given to a command that indicates how it should be
done

bug

a problem in code that either stops the program from running or causes
the program to have unintended results

casting

the process of converting the data type of a variable or value from one
type to another

command

each line of code in a program that tells the computer what to do; a
series of commands builds a program

comments

notes written in the code that the computer will completely ignore

coordinate plane

the flat area defined by an x-axis that runs horizontally (side
to side) and a y-axis that runs vertically (up and down)

debugging

the process of reviewing code and removing any bugs

dot notation

the syntax for assigning an action to a specific sprite using its
variable name

event handler

calls a function when it receives a signal, such as a sprite
collision, mouse click, or key press

event

a block of code that will only run when a certain action happens

float

number with decimal or fractional parts; floats appear blue and are not
surrounded by quotes

indentation

the offsetting of code to separate it as a block from other code
(one indent is 4 spaces or 1 tab)

input variable

a variable that stores the input that a user enters in an ask text
box

integer variable

a variable that stores an integer (whole number) value

integer

negative or positive whole numbers, including zero

logic error

a bug in a program that creates incorrect or unexpected results but
causes no error popup

origin

location (0,0) on the coordinate plane, where the x and y axis cross;
located at the center of the stage in Codesters

point

a location on the coordinate plane defined by x and y-coordinates

program

a sequence of commands that tells the computer what to do

shape

a type of sprite that can have customizable dimensions and color

sprite

a character, shape, or text object that can be added to the stage

stage

the area where the program's visual output is displayed

string concatenation

the process of combining two strings together with the +
operator

string variable

a variable that stores a string value

string

anything in quotes; a string can contain words, letters, sentences, or
symbols

syntax error

a bug caused by incorrect syntax that displays an error popup

syntax

rules that define the way that code must be written

user input

information passed to the program directly from a user

user

someone who will use or is using the program

variable creation statement

uses an equal sign to connect the variable name
to the stored value

variable name

the word to the left of the equals sign that identifies a specific
variable

variable

a name that stores a value

xy-coordinates

two numbers that represent a location on the coordinate
plane; the x-value is first, the y-value is second (also called ordered pairs or
coordinate pairs
