Programming Fundamentals

Hello World, welcome to Dev Terminology, where we talk about dev concepts.
Today’s topic — Programming Fundamentals; the basic concepts of any programming language.
When learning to code programming fundamentals always need to come first. The more you understand them, the easier it is to build upon it and learn advanced concepts.
The Fundamentals of Programming:
- Data Types and Variables
- Operators
- Control Structures
- Data Structures
- Syntax
- Tools
These Programming Fundamentals — Do Or Complete Different Solutions Together.
It's kind of a cheesy line, but I hope you get my drift.
"It's important to remember that a lot of programming languages are very similar, and knowing what's common between all programming languages will help you transition into any other programming language if you need to!" (Trevor Page).
You can call them building blocks, a road map, blueprints, tools even, but regardless of the name, they are a foundation. The fundamentals tell you where we came from, where we've been, and where we're going. They need to be similar across programming languages because it's that similarity that allows each of us, to some extent, to understand them regardless of what language we speak or interact with. It's what allows us to communicate.
Programming Fundamentals Overview
Data Types and Variables
Data Types are the identity of a variable
— an attribute of data which tells the compiler or interpreter how the programmer intends to use the data.
Types of data types:
Boolean, Integer, Float, Character, String,
Nothing Data Types, [Array *], etc ...
Note: know how to convert one data type into another (Data type conversion).
Variables are value placeholders
— an element, feature, or factor that is liable to vary or change.
my_name = "Jane"
In this case, my_name holds the value of Jane.
Operators
Operators are symbols that tell you what to do.
You know like + - = ...
Common operator types include:
arithmetic, comparison, and logical operators.
Control Structures
Control Structures are used to make decisions on what actions to take
— the types of instructions the program should follow.
Types of Control Structures:
Decision control, Selection control,
and Repetition / Loop control.
These control structures may be better known as:
Functions, Collections, Objects, Classes,
Loops, Conditional / If Else statements etc...
Data Structures
Data Structures are ways to manage, organize and access data.
Some general data structures are:
Arrays, Linked Lists, Queues, Stacks, Hash Tables,
Trees, Graphs, Heaps, Matrix, etc...
Syntax
Syntax is the way you order your words.
— The rules, principles, and processes that govern the structure of sentences in a given language.
print("Hello World!")
In this case, this sentence structure is python syntax that when executed will print Hello World!
Programming Tools
Hardware with an operating system — A computer (preferably accompanied by a keyboard and mouse).
Some sort of internet connection — WIFI
A terminal — The command line
Some software — Your language's software developer kit (SDK)
- This is where you click the big download button and let it do its magic
- Example: Python SDK
A code editor, IDE, and/or whiteboard if you prefer
VSCode, Vim, Sublime Text, Whiteboards ... pen and paper?
Version control — Your remote repositories (where you store your code)
Project management tools
CI/CD — continuous integration / continuous delivery
For more information consider going to your local google or other browser if you're alternative.
Final note — When you start your developer journey
- Go slow
- Understand the fundamentals
