This is the first piece of code II've written on my own since I started learning a couple of months ago. The code works and it takes an intint as input and creates a linked list with each node representing a digit.
I've I've added a function that sums two linked listed ints and returns a third list with the result. The rest of the code is also distributed in functions.
Before I move on, it would be greatly appreciated to know if I'm doing something wrong, if my code is properly structured or if I'm following a good/bad style.
