What and Why of Programming – Learn It the Right Way from Scratch

on

When I first started learning programming, I had this one big question in my mind: How does a computer actually know what to do?

Just think about it you open your laptop, click on YouTube, and instantly, videos start playing. You open Amazon, and products show up within seconds. At first, it felt like magic to me. I thought computers were smart on their own. But when I dug deeper, I realized the truth: computers don’t think for themselves at all. They don’t have emotions, they don’t have creativity, and they definitely don’t know what to do unless we tell them.

And that’s where programming comes in.

What is Programming? (My Simple Understanding)

Programming is just giving the computer step-by-step instructions about what it should do.

We write these instructions in a language that humans can understand (like Python, C, or Java). Then that code is translated into something the computer understands (binary: 1s and 0s).

When I first wrote my "Hello World" program, I realized it’s literally me talking to the computer. And the computer responds, but only if I write my instructions clearly. If I miss a step or mess up, the computer won’t guess. It’ll either throw an error or give the wrong output. That’s why I say computers are like super-fast but super-obedient robots. They’ll do exactly what you tell them to, even if you accidentally tell them the wrong thing.

How I Explain Programming to Friends

Here’s how I once explained programming to one of my friends (and it really clicked for him):

Imagine you have a robot in your kitchen, and you say "make orange juice".

Now, the robot doesn’t know what that means. It can’t imagine or figure it out. You have to break it down into exact steps, like this:

  1. Pick 2 oranges from the basket.

  2. Cut the oranges in half.

  3. Put each half in the juicer.

  4. Turn the juicer on.

  5. Pour the juice into a glass.

  6. Add ice cubes.

  7. Serve it cold.

See how specific that is? If you tell the robot "squeeze the orange" before you even cut it, the task fails.

That’s exactly how programming works. You break down a big task into small, ordered steps that the computer can follow.

Why Do We Need Programming?

When I was a beginner, I often thought that, what is the use of learning programming when everything is already built. But then I realized, without programming, computers are useless boxes.

It’s programming that makes them powerful. Here are some things I learned programming allows us to do:

  • Solve problems like doing big calculations, analyzing data, or finding the shortest path on Google Maps.

  • Automate boring stuff. For example, I once wrote a script to automatically organize my messy download folder.

  • Build apps and websites. Every app you use (Instagram, WhatsApp, Spotify) is built with code.

  • Control machines. ATMs, washing machines, traffic signals, even self-driving cars run on code.

  • Work with data. Predicting the weather, tracking stock markets, medical research, all of this needs programming.

That’s when it clicked for me: Programming isn’t just about computers. It’s about solving real-world problems.

My First Small Program (Adding Two Numbers)

One of the first tiny programs I wrote was just to add two numbers. At first, it felt silly. I mean, why write code for something I can do in my head. But when I wrote it, I realized this is the foundation of everything bigger.

Here’s how I did it:

In C

#include <stdio.h>
int main() {
    int a = 5;
    int b = 3;
    printf("%d\n", a + b);
    return 0;
}

In Python

a = 5
b = 3
print(a + b)

In both cases, I was literally telling the computer:

  1. Store 5 in a.

  2. Store 3 in b.

  3. Add a and b.

  4. Print the result.

Simple, right? But the cool part is the same logic applies whether you’re adding 2 numbers or processing millions of transactions on Amazon.

What Programming Really Feels Like

When I started practicing, I realized programming is not just typing code. It’s a full problem-solving process such as

  1. Understand the problem: What do I want the program to do? What’s the input? What should the output look like?

  2. Plan the logic: Break the problem into small steps. Sometimes I sketch a flowchart or just write pseudocode in plain English.

  3. Write the code: Translate the steps into a programming language (Python, C, Java, etc.).

  4. Run the program: Let the computer execute my instructions.

  5. Debug (fix mistakes): Honestly, debugging takes more time than coding. But I’ve learned it’s part of the process.

  6. Test and improve: Try different inputs, check for errors, and make the code faster or cleaner.

Common Misconceptions I Had About Programming

When I was new, I believed a lot of myths. Maybe you’ve heard some of these too:

Programming is only for geniuses: Nope. Anyone can learn with practice. I struggled a lot at first, but step by step, it made sense.
You need to be a math expert: Wrong. Most of programming is about logic and problem-solving, not advanced math.
It’s boring: Honestly, programming is creative! You’re literally building something out of nothing. I still remember the joy of making my first simple game.

What You Can Do With Programming (From My Experience)

Once I got comfortable, I realized the possibilities are endless. With programming, I could:

  • Build my own websites and apps.

  • Create fun little games.

  • Work on AI projects and experiment with machine learning.

  • Analyze data and visualize it.

  • Even control hardware like robots and IoT devices.

It felt like having a superpower where the only limit is my imagination.

Why I Think Everyone Should Learn Programming

After my journey so far, here’s my honest opinion:

Learning programming is one of the best skills you can have today. Because:

  • High demand: Almost every industry needs programmers.

  • Problem-solving: It trains your brain to think logically.

  • Career opportunities: From freelancing to working at big tech companies.

  • Personal growth: You can build tools and apps for yourself.

  • Impact: Your code can literally help thousands or even millions of people.

Final Thoughts (From My Experience)

Computers are incredibly powerful machines. But here’s the thing, without programming, they’re just silent boxes sitting on your desk.
Programming is our way of communicating with them, step by step, telling them what to do. From a simple calculator app to complex platforms like YouTube or Google Maps, it all starts with someone writing code.
For me, programming has been a mix of problem-solving, creativity, and sometimes frustration (debugging nightmares!). But every time I see my code working, it feels worth it.
