Scripting post pre assessment

float

used for numbers with decimal points (heigh, temperature, money with cents)

string

holds one text value

string array

holds multiple text values (like a list of names)

constant integer

used for constants for fixed values that dont change (secondsperminute = 60)

equality operator ==

checks if two values are equal (i == 20 checks if i is 20)

programming library functions

relates to the same purpose

library advantages

pre written & tested / saves time & reduces bugs

dynamically typed language

can assign different types to the same variable (python)

non-object oriented

C is not object oriented, it is procedural (uses functions & data instead of classes and objects)

object orientated language

supports classes and objects with internal data and operations

statically typed language

throws errors when types dont match (Java & C++)

markup language

uses tags to format text (HTML & XML)

interpreted language

runs without compilation and works across different systems like python

advantage of interpreted programs

can be modified at runtime / great for scripting

do-while loop

runs code at least once before checking the condition - perfect for user input loops

pseudocode output

x=3, output is 3 2 1 with a do-while loop

agile implementation phase

when actual code is written

agile design phase

planning the components and features that are needed

waterfall implementation phase

where coding begins after planning

agile analysis phase

review feedback and adjust program goals

agile iterative implementation

each version adds features - implementation continues

algorithm timing

develop the algorithm before writing the program

algorithm example

step by steps (insert key, turn key, open door)

class diagram elements

includes classes, attributes, methods, and relationships
