CODING FOR ABSOLUTE BEGINNERS: How to Keep Your Data Safe from Hackers by Mastering the Basic Functions of Python, Java, and C++ (2022 Guide for Newbies)

INTRODUCTION

So you want to learn to code but don't know where to begin? This book will be your one-stop-shop for all things coding. We'll give you a quick overview of what coding is and how it can help you in any industry, and then we'll explain why it's important for everyone from high school students to seniors. We will also provide some resources for free learning and teaching yourself more advanced skills on your own time.

What exactly is coding?

Coding is the process of converting instructions into a computer language. This code can be understood by the computer, and the code can control how the computer functions, allowing people to achieve their goals. Coding is one of America's fastest-growing and highest-paying jobs. (2015) (Bureau of Labor Statistics) If you've ever used an ATM or a credit card to pay for something, coding was probably involved.

How does it function?

A programmer writes code with the help of special programs on your computer keyboard or a text editor, such as Notepad on Windows or TextEdit on OS X. The code, like the instructions on a piece of paper, tells the computer what to do or how to function. This code can assist a person in doing anything that requires programming skills, such as creating games, connecting electronic devices, programming robots, and much more.

What is the significance of this?

Every industry requires programming skills. Many jobs in technology, such as software engineers, technicians, and IT specialists, require coding. Other positions in technology, in addition to these, do not require programming skills at all, but rather an expertise in specific programs and languages. Coding is frequently used in schools to teach students all of the skills required for academic success a wide range of industries Coding can provide students with the experience they need to make something happen, learn to be self-sufficient and creative, and work well under pressure. There's nothing to be concerned about; it's just programming!

Where can I find out more?

There are numerous resources available on the internet to help you get started. Many resources, such as Codecademy, Code Academy, Lynda.com, and Udemy, are available online for free or for a small fee. You might even want to try your hand at writing code from scratch if you have any ideas. All you need is a computer, an internet connection, and a little drive.

Goals should be coded!

This is just the tip of the iceberg in terms of where coding can take you in your life! You will be able to use this knowledge to learn more advanced skills that will be more meaningful to you on your own time, such as teaching yourself how to use advanced software languages such as C++ or Python. Perhaps you'll become a web designer and build your websites or applications to help you learn more about your abilities. Take advantage of this once-in-a-lifetime opportunity!

Coding is just one step in the larger technology industry, and anyone can take it with you. It's as much fun as it sounds and will teach you skills that you can use throughout your life. We'll see you there if you're ready to dive in!

Definitions of Common Terms

Coding is the process of converting a problem into code or a string of symbols and language that a computer can understand.

HTML: Hypertext markup language, or how your website's information is presented to users. HTML is a markup language that is used to format text, images, links, video, and audio.

JavaScript: A web development programming language that makes it easier to create interactive websites and add effects such as scrolling boxes and drop-down menus. JavaScript enables you to create more dynamic pages that perform faster than static pages produced from pure HTML.

Node.js is a JavaScript framework that enables you to create powerful real-time applications by utilizing an event-driven and non-blocking I/O model.

jQuery: A JavaScript library for rapid web development that simplifies HTML document traversal, event handling, animation, and Ajax interactions.

Responsive Design: The process of adapting a website's design to different screen sizes (smartphones, tablets, laptops, etc.) without affecting the website's layout or functionality.

Test-Driven Development (TDD) is a method or framework for automating software testing that is based on creating test cases from an incomplete specification. It asserts that code should be specified before it is written.

Coding's fundamental terms.

1. Abbreviation : A text or a group of words that has been shortened.

The most common application is to give organizations a short and memorable name so that people can remember them easily. It is also used informally to express complex concepts or ideas by using only a portion of the entire world, which saves time when reading.The abbreviation, as well as typing it For example, Max in Maxwell can also be used to describe a variable in math formulas, and X1000 may be used to describe a million (1000x) rather than an actual number (1x1000).

2. Accessibility : The ease with which content on a website or other media can be accessed. The accessibility of a website is comprised of many different factors, including design, content, and technology.

3.API -API stands for application programming interface. A collection of routines, protocols, and tools used to create software applications.

4. Cache : Temporary storage available on your computer's or mobile device's web browser that stores data faster or more efficiently than it is retrieved from the site itself. It enables the browser to load websites faster by storing frequently accessed web page elements such as text, graphics, and sounds. Caching also allows users to access online information even when no Internet connection is available.

5. Challenge-response authentication : A type of security protocol in which a user is first challenged to provide some information about themselves and then presented with a response based
