So a situation came up at work, it’s a simple enough thing, but I decided that I did not know it thoroughly and in-depth. This post is a result of studying and experimenting for that. Say we have a module in the “server” that takes a data as input and based on the command ID, calls the required handler. There’s 3 ways you can do this. Two of them being almost identical. Here’s the playground:

Going through a 2-D array seems trivial. There’s an inner loop and an outer loop. However, I finally got to understand some concepts I had learned in computer organization theory when I actually tried to access large 2-D array for image processing. Consider the following scenarios for a 2-D Integer array of 20megabytes: int (*arr)[5000] = malloc(sizeof(int[5000][5000])); // Loop 1 -- for (int...

An experiment in threading Introduction I was working on a toy code problem for a simulation for a small contest: We need to find with what probability any two random points chosen inside a square, if taken as the diameter of a circle, the circle will fall inside the square. I was not able to solve this theoretically, so thought, let’s have code solve it. Here’s the code I and my teammate cam...

[WIP] The concept of pointer in C is one of the most feared concepts, but with a little bit of effort, it’s easily understood. However, even after understanding, because there are many small concepts, we need a quick reference that can help us recall the workings. I hope this post serves as both. Q. What exactly is a pointer? A. The K&R book provides the best succinct definition of a poi...
