array.h

a lightweight dynamic (and generic) array type C is missing.

OVERVIEW

This is not a linked list but a dynamic array. Meaning that their elements are just next to each other.
Although removing element in the middle is expensive for this type, every time its capacity hits the limit, realloc occurs for the two times of the last capacity,

so tasks such as keep adding items, overwriting, removing the last element, slicing... are pretty cheap.

USAGE

I'd have totally freed this [word]

hello world and bye world

I'd have totally freed this [world]
I'd have totally freed this [bye]
I'd have totally freed this [and]
I'd have totally freed this [world]
I'd have totally freed this [hello]

---

Being a smart ass, I decided that declare_array(typename) macro to declare ItypenameI struct type that totally looks like [typename].

1. use declare_array(typename) globally to make array type of typename.
2. declare a ItypenameI variable.
3. use II__init(variable, elementwise_cleanup, ...) to initialize an array.
4. profit.

---

If you don't like two underscores (you have every right to be angry about it, but I have my own reasons), or the naming itself, please do change it, instead of swallowing it.

ADVANCED

Use this with defer.h to make the world better place, where the sun is shining, lollipops are singing, rainbows are giggling... and arrays are freeing themselves.
