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.

Focus on the output of mathematical functions and evaluations.

Some popular functional programming languages include:

Programming Process

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

Five Essential Steps to planning your program

4 Basic Flowchart Symbols for Creating a Flowchart

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

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.

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

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

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

Clarify where the data your flowchart references is being stored.

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

Symbols that make easier to connect flowcharts that span multiple pages

Data stored in any format

Data stored locally

Data that must be accept sequentially

Data that can be accessed in any order

Data input into an older computer system

Data manually entered when prompted

Any manual adjustment to the flow

Data being added or pulled from the flow.

Information being show to a user

Point where separate processes join together

Indicates that flow continues on a new page

Used to show flows accross multiple charts or pages

Pre-existing flow defined elsewhere

Beginning or end of the repeated step in the process

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

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

Data Types

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..

Letters or other figures that programmers might combine in a string

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

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

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.

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

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

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.

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."

Contains a value that the code cannot prOcess.
