What is coding?<\/span><\/h2>\n
Coding (also called programming) is the process of writing a set of instructions that a computer can understand and execute. These instructions are written in a specific programming language such as Python, Java, C++, or JavaScript.\u00a0<\/span><\/p>\n
Coding is used to create software, websites, mobile apps, and even control hardware like robots or smart devices.<\/span><\/p>\n
Let us now move on to some technical topics related to computer coding.<\/p>\n
How Does Coding Work? A Question for the Curious<\/h2>\n
In order to make a computer understand your instructions, you need to choose a suitable means of communication. Computers can only comprehend machine language (binary code). However, instead of learning to code in binary language, you can learn assembly language or other high-level languages.<\/p>\n
Assembly language, although much more powerful than high-level languages, is still a lot like machine language. Therefore, it is relatively hard to learn. High-level languages are very similar to the languages that humans communicate in, such as English. Hence, they make computer coding much easier.<\/p>\n

How Does Coding Work<\/figcaption><\/figure>\n Once you have learned a high-level language, you use it to write instructions. This collection of instructions is called a program. The program is first converted from high-level language to assembly language with the help of a compiler or interpreter. The assembly language is further translated into machine language.<\/p>\n
Once the computer is able to understand what you are saying, it knows exactly what to do. Your code is successfully executed when the program \u201cruns\u201d and carries out your instructions.<\/p>\n
What Is Coding Used For?<\/h2>\n
You must now be thinking, \u201cWhat can coding be used for?\u201d<\/p>\n
There are numerous applications of computer coding. One of the most common ones is seen in the form of desktop applications. These are programs that you use on your computers or laptops. For example, a word processor, such as Microsoft Word, has many lines of code behind it.<\/p>\n
Making desktop apps is not the only purpose of coding. There are many other areas that can be used. Take a look at the following tasks:<\/p>\n
- \n
- Developing a new operating system for PC<\/li>\n
- Creating a mobile application, such as a new Music Player<\/li>\n
- Setting up a website, such as a personal blog<\/li>\n
- Instructing a microwave on how to heat food<\/li>\n
- Coming up with a new MMORPG that people can play with their friends on PC or phone<\/li>\n<\/ul>\n
This is just a fraction of what coding can be used for. There are thousands (sometimes even millions) of lines of code that enable you to perform these tasks. Therefore, this is all part of what coding is.<\/p>\n

Types of Coding Languages: A Few Basic Concepts<\/h2>\n
Coding involves writing many different types of programs to perform a variety of tasks. You choose a language depending on your needs.<\/p>\n
Each coding language has its own syntax, i.e., rules, just like the English language has some grammar rules.<\/p>\n
There are a few programming languages that have been a popular choice among coders for the past few years. Let us talk about some of the most common coding languages:<\/p>\n
- \n
- Java<\/li>\n
- Python<\/li>\n
- PHP<\/li>\n
- HTML<\/li>\n
- CSS<\/li>\n
- C++<\/span><\/li>\n
- Ruby<\/span><\/li>\n
- SQL<\/span><\/li>\n<\/ul>\n
Java<\/h3>\n
This is one of the few programming languages that are taught to Coding 101 students. Many people believe that it is one of the languages that is easiest to learn. It is very similar to C when it comes to syntax. However, unlike C, it is an object-oriented language (let\u2019s leave that for another time though!).<\/p>\n
One of its major advantages is that it is machine-independent. However, for development, you will need Java SE installed on your machine.<\/p>\n
Java is a multipurpose language. Its applications include the development of browser-based, mobile, and desktop apps.<\/p>\n
Let\u2019s take a look at one of the beginner Java lessons, which makes use of the print function.<\/p>\n

str():<\/strong> declare empty string<\/p>\n
max()\/min():<\/strong> return maximum\/minimum from list of given values<\/p>\n
sum():<\/strong> return the total of given values<\/p>\n
PHP<\/h3>\n
PHP is a scripting language that is used in writing server-side code for websites. It provides a communication channel between the web server and the browser.<\/p>\n
There are a number of reasons why PHP is given preference over other scripting languages.<\/p>\n
- \n
- It is free and open-source.<\/li>\n
- It is extremely easy to learn.<\/li>\n
- PHP has been a favourite of programmers for the past few years. Therefore, it has seen a lot of growth and improvement, making it a good choice for both beginners and experts.<\/li>\n<\/ul>\n
This is how you write a basic PHP script, i.e., the part that is enclosed in the <?php> \u2026 <?> tags.<\/p>\n

More commonly known as CSS, Cascading Style Sheets is used by developers to enhance website design and layout. They are a means to beautify webpages. Using CSS, you can define the font styles, sizes, colours, and various other design elements for the layout of your webpages.<\/p>\n
CSS code usually follows this syntax:<\/p>\n
selector \r\n{ \r\n property: value;\r\n}<\/pre>\nIf you wanted all your headings to be coloured white with a black background, this is how you would code it in your stylesheet:<\/p>\n
h1 {\r\n color: white;\r\n background: black;\r\n}\r\n<\/pre>\nHTML<\/h3>\n
HTML (Hypertext Markup Language) is one of the most common coding languages used for web development. HTML tackles the following questions:<\/p>\n
- \n
- What content will be displayed on your webpage?<\/li>\n
- How will it be displayed on the screen?<\/li>\n<\/ul>\n
The language is based on pairs of tags (included in angle brackets, e.g., <tag> <\/tag>), which help identify and define the elements on your webpage.<\/p>\n
For example, this is the code for including a heading on your page:<\/p>\n
<h1>\r\n This is a heading.\r\n<\/h1>\r\n<\/pre>\n
Similarly, a paragraph is represented by <p> and an image by <img>.<\/p>\n
Remember to always close your tags.<\/p>\n
Here is an example of coding in HTML and CSS combined:<\/p>\n

#include <iostream>\u00a0 \/\/ Header file for input\/output<\/span><\/p>\n
using namespace std;<\/span><\/p>\n
int main() {<\/span><\/p>\n
\u00a0\u00a0\u00a0\u00a0cout << “Hello, World!”;\u00a0 \/\/ Prints message to the screen<\/span><\/p>\n
\u00a0\u00a0\u00a0\u00a0return 0;\u00a0 \/\/ Indicates successful execution<\/span><\/p>\n
}<\/span><\/p>\n
Output<\/span><\/h4>\n
Hello, World!<\/span><\/p>\n
This simple program prints “Hello, World!” to the screen.<\/span><\/p>\n
Ruby<\/span><\/h3>\n
Ruby is a dynamic, high-level, and object-oriented programming language known for its simplicity and readability. Ruby provides an elegant and expressive syntax that closely resembles natural language. It is fully object-oriented, meaning everything in Ruby, including numbers and functions, is treated as an object.\u00a0<\/span><\/p>\n
Ruby is widely used in web development, particularly with the Ruby on Rails framework, which simplifies building robust and scalable web applications. It supports multiple programming paradigms, including procedural, functional, and object-oriented styles, making it highly flexible.\u00a0<\/span><\/p>\n
Ruby also features automatic memory management and dynamic typing, reducing the complexity of code writing. With an active community and a wealth of open-source libraries, Ruby continues to be a powerful choice for developers focused on rapid development and maintainability.<\/span><\/p>\n
Example of Ruby Code<\/span><\/h4>\n
puts “Enter your name:”\u00a0 # Prints message to the console<\/span><\/p>\n
name = gets.chomp\u00a0 # Takes user input and removes the newline character<\/span><\/p>\n
puts “Hello, #{name}! Welcome to Ruby programming.”\u00a0 # Prints a personalised greeting<\/span><\/p>\n
Output<\/span><\/h4>\n
Enter your name:<\/span><\/p>\n
Alice<\/span><\/p>\n
Hello, Alice! Welcome to Ruby programming.<\/span><\/p>\n
SQL<\/span><\/h3>\n
SQL (Structured Query Language) is a specialised programming language used for managing and manipulating relational databases. It allows users to create, retrieve, update, and delete data efficiently using simple and structured commands.\u00a0<\/span><\/p>\n
SQL is widely used in industries that rely on data storage and management, including finance, healthcare, e-commerce, and social media platforms. It is a declarative language, meaning users specify what they want to retrieve rather than detailing how to get it.\u00a0<\/span><\/p>\n
Popular database management systems that use SQL include MySQL, PostgreSQL, Microsoft SQL Server, and Oracle Database. Due to its efficiency and scalability, SQL remains the backbone of modern data-driven applications, making it an essential tool for data analysts, developers, and database administrators.<\/span><\/p>\n

What is the process of writing code?<\/span><\/h2>\n
The process of writing code generally follows these key steps:<\/span><\/p>\n
1. Understanding the Problem<\/span><\/h3>\n
Before writing any code, it is crucial to understand the problem that needs to be solved. This involves defining the requirements, identifying constraints, and clarifying the expected output.\u00a0<\/span><\/p>\n
Developers often work with stakeholders, clients, or team members to gather information and ensure they fully grasp the scope of the project. A <\/span>statement of work (SOW) document<\/span><\/a> is often used in this stage to outline the project’s objectives, features, technical requirements, timelines, and scope.<\/span><\/p>\n
2. Planning the Solution<\/span><\/h3>\n
Once the problem is well understood, the next step is planning how to solve it. This includes choosing the appropriate programming language and tools based on the project\u2019s needs.\u00a0<\/span><\/p>\n
Developers also design the program\u2019s architecture by outlining its structure and workflow. Techniques like writing pseudocode, creating flowcharts, or using Unified Modeling Language (UML) diagrams can help visualise the solution.\u00a0<\/span><\/p>\n
3. Writing the Code<\/span><\/h3>\n
