is the process of writing code to facilitate specific actions in a computer, application or software program, and instructs them on how to perform.

professionals that create instructions for a computer to execute by writing and testing code that enables applications and software programs to operate successfully.

Computer Programmer

Focus on the output of mathematical functions and evaluations.

Functional Programming Language

Some popular functional programming languages include:

Scala, Erlang, Haskel, Elix, IR

Programming Process

defining the problem, planning the solution, coding the program, testing the program, documenting the program

is a process of determining which process will own CPU for execution while another process is on hold.

CPU Scheduling

Five Essential Steps to planning your program

Assess the problem, Study current community efforts, Study best practices in the field, Establish partnerships, Complete a program logic model

4 Basic Flowchart Symbols for Creating a Flowchart

oval or terminator, rectangle, arrow, diamond

This symbol is used to represent the start and end of a process.

oval or terminator

This symbol is your go-to symbol once you've started flowcharting. It represents any step in the process you're diagramming and is the workhorse of the flowchart diagram.

rectangle

This symbol is used to guide the viewer along their flowchating path.

arrow

This symbol symbolizes that a decision is required to move forward.

Diamond

icons show that there are additional points of reference involve in your flowchart.

Single and multiple document icons

Clarify where the data your flowchart references is being stored.

data symbols

Symbols that show where and how data is coming in and out throughout your process.

Input and output symbols

Symbols that make easier to connect flowcharts that span multiple pages

Merging & Connecting Symbols

Data stored in any format

Data Storage

Data stored locally

Internal storage

Data that must be accept sequentially

Tape data

Data that can be accessed in any order

Database

Data input into an older computer system

Paper Tape

Data manually entered when prompted

Manual Input

Any manual adjustment to the flow

Manual Operation

Data being added or pulled from the flow.

Input/output

Information being show to a user

Display

Point where separate processes join together

Merge

Indicates that flow continues on a new page

Off-page connector

Used to show flows accross multiple charts or pages

Connector

Pre-existing flow defined elsewhere

Predefined process

Beginning or end of the repeated step in the process

Loop limit

Defines a waiting period that part's of the flow.

Delay

Is an attribute of a piece of data that tells a device how the end user might interact with the data.

Data Type

Data Types

Integer, Floating point (real), Character, Long, Short, String, Boolean, Date, Nothing, Void

Often represent whole numbers are digits that account for whole programming. A value moves from one numbers to another without acknowledging fractional numberts in between..

Integer

Letters or other figures that programmers might combine in a string

Character

Type of data that stores a calendar date with other programming information.

Date

Data types represent fractional numbers in programming. Vary depending on the number of allowable values in the string

Floating point (real)

Data types are often 32- or 64-bit integers in code. Sometimes, these can represent integers with 20 digits in either direction, positive or negative. Programmers use an ampersand to indicate the data type is a long variable.

Long

A variable integer that programmers represent these as whole numbers, and they can be positive or negative.

Short

This data type is a combination of characters that can be either constant or variable.

String

Data is what programmers use to show logic in code. It's typically one of two values-true or false-intended to clarify conditional statements. These can be responses to "if/when" scenarios, where code indicates if a user performs a certain action.

Boolean

Data type shows that a code has no value. This might indicate that a code is missing, the programmer started the code incorrectly or that there were values that defy the intended logic. It's also called the "nullable type."

Nothing

Contains a value that the code cannot prOcess.

Void
