Coding vobab Flashcards
World
A world or Karel world is a grid that karel lives in.
Karel
Karel is a dog who listens to your commands
Command
A command is an instruction you can give to Karel
Function
teach a computer a new command it should do when command
Call a function
Calling a function actually gives the command so the computer will run the code for that function.
Indentation
Indentation is the visual structure of how your code is laid out. It uses tabs to organize code into a hierarchy
Curly Bracket
an open curly bracket is(and a close bracket is)
Parentheses
(and)
Function body
The part of a function that contains the commands,
Define a function
Means to teach the computer a new command and explain what it should do when receiving that command.
Break down (Decompose)
breaking down(decomposing) your code is splitting it into more functions
read like a story
programs that read like a story have good decomposition and make the code easy to follow
Indentation
indentation is the visual structure how your code is laid out. It uses tabs to organize code into a hierarchy.
start function
this is the function that is called when you click run.
decomposition
decomposition is breaking your program down into smaller parts
Top down design
top down design is a method for breaking our program down into smaller parts
Algorithm
An algorithm is a set of steps or rules to follow to solve a particular problem.
Conditions
A condition is code that you put inside an if statement or while loop
if statement
An if statement lets you ask a question to the program and only run code if the answer is.
If else statement
Control structure that lets us do ether one section of code or another depending on a test
Control Structure
A control structure let us change the flow of the code
loop
A loop is way to repeat code in your program
While loop
Lets us repeat code as long as something is true
Fencepost Problem
A problem when using a while loop where you forgot one action at the beginning or the end.
Collage
a collection of images
Filter
a software routine that changes the appearance of an image by altering the shades and colors of the pixels in some manner.
color Saturation
the intensity of a color expressed as the degree to which it defers from white.
Contrast
the difference in brightness between objects or regions.
Brightness
the overall lightness or darkness of the image.
inversion
the act of switching colors along the color wheel(red to green, blue to orange,etc)
Image filter
a procedure that applies a particular function to an image’s pixel to change its appearance.
Gif
graphics interchange format, an image format that allows animation
Scene
one image in series of image’s that make up a gif
