This probably happens to everybody that when coding, not everything goes as you expect logically. Like, why the heck such a simple code is not able to access array elements inside a for loop? It's such a simple thing. Where is this segmentation fault coming from???
Things really do get crazy sometimes. There are always bugs that may take from 5 minutes to a few weeks to find the solutions of (at least for me.) I wanted to make use of the time I spend on this bugs and document how I solve them; make them more than just some bugs and create a "reverse Stackoverflow" where instead of getting mean reactions when you ask questions, I'll answer some questions which I've faced, before the next person with similar problems asks them haha!
So the following will be the problems that I've faced by far, all during doing the projects of Funktional Stdo and how I've solved them. I hope these become useful to somebody!
