On the Quest of recoding malloc(3)

Back when I did not know anything about programing and started to learn C, I was first introduced to pointers (and other dreaded horrors that made me curl into a corner and cry) and dynamic memory in general.

I was baffled, troubled, yet fascinated by the basic explanation on how memory worked, and started to dread the time where I would need to manually create my char arrays for each and every sentences of my program; right before learning about string literals and feeling like an idiot.

It was then where I was learning about memory allocation and came upon a function that I would call for long the "magic function" : malloc. Magic, because at that point I didn't know how it worked, let alone knew anything about memory other that it was a "chain of boxes for numbers".
