I: Introduction

1. What are Programming Languages?

Programming languages are used to create programs that can be executed by a computer. The programming language is the medium that communicates the instructions to the computer. These instructions are written in a language that humans can understand, but computers can understand them through their machine language.

2. Basic Coding Terminology

Coding is the process where you write source code using a programming language. Source code is the language that humans can read and understand. For example, if you are writing an article, you are writing your source code.

The codes are stored so that they are not lost when you are done writing. This is called compilation. This means that when you close your program, or quit writing your article, what you have written disappears. If you try to open your file again, it will be empty. This is how it works in all languages, so you will never lose anything.

When you need to run your code, you will compile it into a file that is executable. When you run your code, it will be executed in the same way that the application was compiled. When we compile and execute our project, we get a binary version of our code.

You can edit and run the code in many ways: in an integrated development environment (IDE), in a command line interface (CLI), or in an online editor. If you install Python, you will find an IDE called IDLE. You can also use PyCharm, Komodo Edit and KDevelop. Even if you don’t like these IDEs, you can still use one of the most popular CLI editors: Vim, Emacs and Nano.

3. Popular Programming Languages

Programming languages come in various different types that each have their own features and applications. Some of the most popular programming languages include: C++, Java, Python and PHP. However, there are thousands upon thousands of programming languages available to users today!

4. C++ Programming Language

C++ is a popular programming language used for developing games and apps or for developing software for running on systems or embedded systems. It is one of the most widely used programming languages because it has a wide variety of applications and is flexible enough to be used in a variety of different situations while being easy to learn for beginners. C++ is based on the C programming language with a few additions to simplify memory management issues. There are some differences between C++ and C such as the use of classes and operators. Originally created by Bjarne Stroustrup in 1983, C++ is still growing from its original source code and new versions continue to be developed today. Because of its widespread use, C++ is one of the most stable programming languages for beginners to learn today!

5. Java Programming Language

Java is a general-purpose programming language that was designed to be platform-independent. This makes it very flexible and powerful because it can be used on any device without having to worry about compatibility issues! It was created by Sun Microsystems in 1995 and was initially used for media applications such as video games and animation before becoming more widespread than just media applications. It has since become quite popular in the creation of web-based software and mobile apps! Many popular companies rely on Java to provide their products with reliable, powerful apps including Amazon, Apple, Google, Facebook, Netflix and Twitter just to name a few! Java programs are compiled rather than interpreted so it may seem like there is a little bit more work involved when developing apps in Java compared to other languages but this allows them to run faster than other programs so it’s worth it! Java may seem like a difficult language to learn at first glance but it’s actually quite easy to get started with! Beginners can learn how to program in Java by following free tutorials online or reading books like Learning Java by Cay S Horstmann or Expert One On One JAVA 2 BY Tomcat 6 EPUB PDF by Cay S Horstmann!

6. PHP Programming Language

PHP is another general-purpose programming language that is often used for developing dynamic websites or web apps. It’s often used to power content-management systems like WordPress because it’s easy to use and has many extensions available for developers to use in their projects. PHP stands for “PHP: Hypertext Preprocessor” which means that it was originally designed for creating dynamic websites but over time became more common for use in other kinds of applications as well! PHP is very easy to use even for beginners because it uses plain English for its syntax which means that anyone who knows how to speak English can probably figure out how to code in PHP! PHP does have some downsides though because it doesn’t have support for object-oriented programming so if you want to develop complex applications then PHP might not be the best option for you! PHP has been around since 1990 when Rasmus Lerdorf created it so it’s one of the oldest programming languages still being actively updated today! Some popular books for learning PHP include PHP 7 Developer’s Handbook EPUB/PDF/MOBI/AZW3 by David Powers or Professional PHP Design Patterns Guide EPUB/PDF/MOBI/AZW3 by Lukasz Jelen & James Hartig!
