Perfect beginners guide to the world of writing codes and Computer programs

Author: Kingsley Mayor Omenaiko

Coding has become crucial to INFORMATION TECHNOLOGY. Computer coding and programming are skills that are in high demand.

With the current dispensation and the subsequent automation of everything previously done manually by man, the need to learn an I.T skill becomes very essential.

That is why I prepared this article in order to Introduce some basics on how to code, as well as some links to free coding courses.

Definition of Coding

Coding is a broad term that is very ambiguous. In the context of our subject, it simply means the act or process of writing or preparing codes or instructions that direct the computer on what to do.

The first thing to understand about coding is what a computer code is.

At its core, computer code is a language. Computers themselves only truly ‘understand’ one language, which is called binary or machine language

This mathematical language is composed of ones and zeros, which basically represent ‘on’ and ‘off’ functions.

However, binary is complex and doesn’t translate well into the languages we speak and understand.

Code in the context we’re talking about. it is basically an intermediary between the language of humans and the language of computers.

Coding is the process of writing this intermediary language (code) with the aim of getting a computer to perform certain tasks.

Of course, this is a very simple explanation, and there is a lot more to it.

For example, various programs are needed to translate and carry out the code, and there are many different coding languages, as well as many different purposes.

What are the different types of Coding

  • High-level languages are more programmer-friendly, easy for humans to understand, maintain and troubleshoot.

These include the most common coding languages around today, and we’ll primarily focus on these.

  • Low-level languages are more machine-friendly, making them more memory-efficient and faster to execute.

They are usually used for specialist hardware and are harder for humans to understand.

There are also several different styles of coding, known as paradigms, which are used to solve various different problems.

We’ll not get into a detailed explanation as to the many coding paradigms, but we have outlined some of the main terms below:

  • Object-oriented
  • Functional
  • Procedural
  • Database
  • Logical
  • Structural

These different paradigms and levels are used for all kinds of projects, job roles, and purposes.

Whether it’s developing applications, creating websites, analysing data, or managing databases, there are different coding languages suited to different tasks.

What are the coding languages I can learn ?

There are several programming languages which can actually learn, ranging from current and outdated. But everything depends on the individual’s choice.

Below is a list of recommendation:

  • Python
  • Java
  • JavaScript
  • C#
  • C/C++
  • Visual BASIC

Coding and Programing

Coding is the process of writing code – producing commands that a computer can understand in a language understood by humans.

Programming is the process of creating a functioning computer program or piece of software.

So, coding is an essential part of programming, but the latter requires a host of additional skills and knowledge.

Note that a collection of Computer programs gives rise to a SOFTWARE. The development of a software is borne out of team work.

Why do I need to learn to code ?

Whether it’s for your career or as a hobby, there are plenty of reasons why you might want to learn to code:

There are many reasons you might want to figure out how to learn to code, including:

  • It teaches hard and soft skills

Being able to program and write computer code is a hard skill that has many applications.

And, whether you learn a coding language for a specific reason or simply as a hobby, it also teaches a variety of other soft skills. Creativity, problem-solving, analytics, and logical and abstract thinking are all associated with coding and programming.

  • It helps to expand one’s knowledge base and capacity through rigorous steps which it entails
  • Jobs are in demand

LinkedIn recently released a report on the most in-demand hard and soft skills that employers are looking for.

Areas like blockchain and data analytics often require at least some knowledge of computer code.

Similarly, careers in UX design and scientific computing are based on a strong understanding of programming principles.

Learning to code can benefit your career now and in the future.

  • Coding means flexibility

Programming is a skill that gives you many options. Not only does it mean that you can solve problems in a variety of different ways, but it also gives you flexibility in your career.

You can utilise the skills you acquire in all kinds of job roles and for many purposes.

Career opportunities in Coding

  • Software developers. This role is one of the most in-demand jobs across the world. Software developers create and enhance applications and software across computers, smartphones, tablets, and other devices.
  • Web developers. Those who work in this career focus on the look and functionality of websites, whether it’s the front-end (user side) back-end (database side) or both.
  • Systems analyst. A systems analyst explores how a business’s hardware, software, and IT systems perform. They recommend, build, and implement new technologies and systems to help their clients.
  • Data scientists. This role is focused on leveraging the use of big data to provide insight and analysis. Various programming languages are used to help organise and structure large sets of data.

Learning how to code

  • Choose a coding language

Whichever language you choose, it’s going to take time and effort to learn it.

As such, you might not want to spend time jumping between the various options before finding one you like.

To make things easier, you should think about your aims and do some research.

  • Find an online course on the chosen language and enrol. You could as well hire someone to teach you in person.

Another option is to do it yourself, that is by learning by yourself. You could watch videos on YouTube ( or take tutorials on W3schools ( ), wikiHow ( ), e.t.c.

  • Finally, initiate the habit of practicing in your own. With this you have taken your first journey to the world of Coding and programing.

If you are consistent and focused enough, with time you will become a professional. But ensure you choose current programming languages that are in demand.
