Ap CSP Flashcards (2.1-2.4)

Algorithm

Algorithm

A process or set of rules to be followed in calculations or other problems solving operations

Sequencing

logic structure where instructions are executed in order, one after another, one at a time. Often called linear (Getting Dressed: put on pant, shoes, shirt)

Flowchart

a simple diagram with symbols showing the "flow" of a process

Flow Pattern

pattern that can emerge when data is transformed using computational logic structures (sequencing, selection, iteration).

Sequencing/Sequential Execution

program instructions that are executed one at a time, in order. (One line at a time from the top to the bottom of your program).

Algorithmic Logic Structures

Sequencing, Selection, Iteration

Code Segment

refers to a collection of program statements that are part of a program.

Program

a collection of program statements that performs a specific task when run by a computer. A program is often referred to as software.

Parameter

a variable that defines a procedure or sets the conditions of an operation 

Procedure

a named collection of steps in an algorithm that can be reused anytime it is needed without restating the detailed procedures (abstraction)

Comments

an annotation in the code of a computer program

Remix

to modify and share a version of an uploaded existing project

Pseudocode

• an informal method of writing algorithmic instructions that do not necessarily follow grammatical rules and syntax of a particular language. "False" code. 

• Use it to be concise (basic text language can get wordy) and precise (abbreviations run the risk of leaving out important info)

If Statements

• Only execute if a specific condition/criteria is met.

• ex. If it is raining, then I will carry an umbrella.

If Else Statements

• similar to if statements but focuses on what is to happen when a condition isn’t met.

• ex. If it is raining outside carry an umbrella, else say “hooray”

Statements with Comparison

• are if statements used to compare quantities

• Ex. What is your agre? , IF answer >= 18 say you are eligible to vote, ELSE say you are not eligible to vote. This basically compares the age to the number 18.

( Defintion) Operators

Definition : Symbols that imply a comparison in conditional selection statements.

Operators

• a = b OR == means equal to

• a ≠ b OR != means NOT equal to

• > means greater than

• < means less than

• a ≥ b OR >= means greater than OR equal to

• a ≤ b OR <= means less than OR equal to

Selection

algorithmic structure that uses "if...then" to tell the computer how to select a step or to tell the sequence that should be executed.

Iteration

a function that repeats a block of code in a specified order, often until a specific result occurs. (x=1, add 1 until x>10)

Reptition

in a program means that lines of code will be run multiple times.
