Welcome to C language tutorial. Before digging into C language, let me explain my intention behind writing this tutorial. You can find a lot of tutorials and books online and offline on C language. They all are well written by their writers. Just like every writer have his/her own way of writing or understanding on a concept, I also have my own way of understanding and I want to share my understanding on C Language so that one can get benefited directly or indirectly.
I always follow WWH Theory (My own way of understanding) to understand/ learn anything. Now there will be an obvious question that will came in your mind is “What is WWH theory?”.
Let’s first understand the WWH theory.
What is WWH theory?
It is a set of three questions that I always ask to understand anything. Getting answer to these questions will confirm the understand on that concept. So, if you want to learn any concept or understanding anything using WWH Theory, you need to find fair answer of these three questions and once you got the answer to all these questions, I certainly say that you learn that concepts. So, what are these three questions?
Here, WWH stands for “What“, “Why” & “How“.
W (What): “What is it?”. It is about the thing. With this question you will get basic knowledge about that thing.
W (Why): “Why is it required or why is it needed?”. With this question you will know about its requirement.
H (How): “How can it achieve?”. With the help of above two questions, you know about the thing and it’s need. Now you need to find the way to achieve it. So, this is about the way or method will be used to accomplished it. I hope it is clear. If not, don’t worry you will understand when will go through the tutorial.
I have divided the complete C language tutorial in small modules to make it easy and we will understand these modules with the help of WWH Theory.
Hope you like it …
