CompSci Vocab

Variable

a named place in computer memory that holds information

User

the individual and/or group that uses your program

User Concern

a problem that the user may have that your program can help solve

User Interest

a reason why your user would want to use your program

Algorithm

an ordered sequence of instructions

Conditional

an expression that can be either true or false

Sequencing

instructions in ordered steps

Selection

deciding which step to go to next based on a condition

Iteration

repetition of some steps

List

an ordered sequence of data elements

List Traversal

going through a list, looking at each element one at a time

Procedure

a named process that implements an algorithm (aka - a function)

Procedure Definition

where the functionality of what the named procedure does is established

Procedure Call

executing the function by invoking its name

Parameters

the variables that act as inputs to a function in its definition

Arguments

the actual values passed to the parameters in the function call

Abstraction

a simplification or generalization of something much more complex

Procedural Abstraction

give a name to a process by defining a function that implements a particular algorithm

Paramaters

further generalize a process by making your function even more useful and customizable, enabling it to do its job with various values as arguments

Data Abstraction

giving data a name without worrying about the specific data value in order to manage the complexity of the code

what do you submit on college board digital portfolio?

1. a PDF of all code

2. a screen recording of you running and using the program

3. four screenshots of parts of your code

   • function definition, function call, list storing data, list being used (traversal)

In the creative performance task you will

 you will design and implement a program that might (1) solve a problem, (2) enable innovation, (3) explore personal interests, or (4) express creativity.

how much time to complete the project?

9 hours of class time

Component A requirements

1. Instructions for input from either the user, device, online data, or a file

2. use of one list to represent a collection of data that is stored and used to manage program complexity and help fulfill the programs purpose

3. at least one procedure that contributes to the programs intended purpose, where you have defined the procedures name, return type, and parameters

What does Component B need?

input to program, functionality of the program, and output of program

What can Component B not contain?

any information about yourself, voice narration, or collaboration

The first and second program code segments of Component C must do what?

1. defines the procedures name and return type, contains and uses one or more parameters that have an effect on the functionality of the procedure, implements an algorithm that included sequencing, selection, and iteration

2. shows where your student developed procedure is being called in your program

teh first and second progra code segments of Component B must do what?

1. show how data ha been stored in the list

2. show the data in hte same list being used, like creating new data from existing data, accessing pultiple elements in the list, as part of fulfilling the programs purpose
