Offsetof
Okay kiddo, imagine you have a toy box with lots of toys inside and you want to find a certain toy. One way to do this is to count the number of toys before the one you want and use that number to remember where the toy is.
Well, in computer programming, we have something similar called structures. A structure is like a toy box that holds different types of data. Sometimes we need to know how far away a certain piece of data is inside the structure so we can access it.
That’s where offsetof comes in. It’s a fancy word that tells us how many bytes we need to move from the beginning of the structure to get to a particular piece of data inside it. It's like counting the number of toys to find the one you want in the toy box.
For example, if we have a structure that has a name, age, and address, we might want to find out how many bytes we need to move to get to the age data. Offsets give us that number, so we can easily access that data without counting every time.
So, just like counting toys to find the one you want in your toy box, offsetof helps computer programs find the data they need inside a structure. It’s a neat trick that makes programming a lot easier!
