What Is Coding | Role, Working, How To Learn & More Simplified

Wondering what is coding? Or how does it work? Well, in simple words, a code is what lies behind every technology that we interact with on a daily basis. Coding is the art of writing instructions to computers in programming languages to get them to behave just like you want them to.

In short, coding is the process of writing instructions in computer-readable languages to be executed by computers. It is not surprising to note that the coding and tech world has been growing at an exponentially high rate in recent years, with a massive rise in the number of job opportunities in this industry. In this article, we will discuss what is coding, how it works, how you too can become a coder, some popular languages and more.

What Is Coding?

Computer code refers to a sequence of instructions written using various programming languages, combining symbols and text to communicate with machines. There are different types of codes, such as byte code, machine code, and binary code.

• Coding is the process of creating instructions for computers using programming languages. These instructions (code) tell a computer what actions to perform and how to perform them.
• The purpose of coding is to open up a pathway of communication between machines and humans. It is the backbone of all software, applications, and websites we use daily, from simple calculators to complex social media platforms.
• In essence, when you write code, you are essentially writing a series of commands in a specific syntax (source code) that a computer can interpret and execute.
• It allows one to create instructions for a computer, enabling it to perform various tasks, from simple calculations to complex operations in software development, data analysis, artificial intelligence, machine learning, controlling hardware devices, and more.

Coding is a crucial skill in the modern world, enabling the creation of software that drives innovation, efficiency, and automation in various industries. Note that coding is a subset of programming but is often referred to as computer programming. We will discuss the differences between coding and programming in later sections.

Real-life example of coding- Consider you want to make a sandwich. The recipe requires ingredients like two slices of bread, peanut butter, jelly, and utensils like a knife and a plate. The instructions to make the sandwich might look something like this:

1. Get bread: Open the bread bag and take out two slices.
2. Spread peanut butter: Use the knife to spread peanut butter evenly on one slice of bread.
3. Spread jelly: Use the same knife to spread jelly on the other slice of bread.
4. Assemble the sandwich: Carefully place the jelly-covered slice on top of the peanut butter-covered slice, matching the edges.
5. Cut sandwich: If desired, use the knife to cut the sandwich in half, making two triangles.
6. Serve: Place the sandwich on a plate and enjoy!

In coding terms, this recipe would look something like this:

get_bread()
spread_peanut_butter()
spread_jelly() assemble_sandwich()
cut_sandwich(optional)
serve()

Here, each line of code represents a specific instruction (in the form of functions) for the computer to follow, just like each step in the recipe.

This illustrates the process of writing code, where instructions are meant to get a computing device to do something. The language in which this code is written can be a low-level language (closer to binary code) like C, C++, or assembly language or a high-level language (closer to human language) like Python or JavaScript.

How Does Coding Work?

We now know what is coding, so let's discuss how code works. Evidently, computers are machines that don't understand regular human language because they communicate in a binary language made up of 1s and 0s.

However, it is difficult for humans to write binary codes (i.e., in machine language/ 0s and 1s). This is where programming languages and coding come into the picture. Humans can write codes in programming languages. Coding works by translating these human instructions into a format (machine language/ binary language) that computers can understand and execute.

Here's a step-by-step breakdown of how coding works:

1. Choose a Programming Language: Different programming languages are suited to different tasks. Popular languages include Python, JavaScript, Java, C++, and Ruby.

2. Write Code: Using a text editor or an Integrated Development Environment (IDE), you write the instructions in the chosen programming language. These instructions are written in a specific syntax that the language defines.

3. Compile or Interpret the Code: Depending on the language, the code is either compiled or interpreted. Compiled languages, like C++, require a compiler to translate the code into machine language before execution. Interpreted languages, like Python, are executed line by line by an interpreter.

4. Execute the Program: Once compiled or interpreted, the computer executes the code. It follows the instructions precisely, performing tasks such as calculations, data processing, or interacting with hardware.

5. Debugging and Testing: Coding often involves testing the written code to ensure it works as intended. This step includes debugging, which is the process of identifying and fixing errors or bugs in the code.

6. Iteration and Improvement: Coding is an iterative process. Based on feedback and testing results, you refine and improve the code to enhance functionality, performance, and efficiency.

By understanding these steps, you can see how coding transforms ideas into functional software that powers the digital world. This process of how coding works is explained in the image below.

In simple terms, this is how coding acts as a communication bridge between humans and machines. Where humans write codes and a compiler then expresses these instructions (i.e. lines of code) into machine language for computers to understand and follow through.

Now, let's look at an example code written in Python, a popular programming language. In this program/ code, we will illustrate how to calculate the average of a few numbers.

Code Example:

Output:

The average is: 15.0

Explanation: 

1. Define a list of numbers: We create a Python list called numbers that contains five integers.
2. Initialize a variable: We initialize a variable called sum_of_numbers to 0; this will be used to store the sum of the numbers.
3. Iterate through the list and calculate the sum: We use a for loop to iterate through each number in the list and add it to the sum_of_numbers.
4. Calculate the average: We divide the sum by the number of elements in the list to calculate the average.
5. Print the result: We use the print() statement to display the calculated average.

This simple example source code demonstrates the fundamental concepts of coding: variables, loops, and basic arithmetic operations.
