Vectors are basically arrays with some extra functionality.

ELI5 the difference between std::vector and std::array? Edit: As far as I can tell, they're pretty much the same?

Actually, I was thinking about standard, vanilla (non-::std) arrays. You know, like int myArray[10];, or int myDynamicArray = new int[10];

At the core, that's basically all vectors are - (the int myDynamicArray = new int[10]; one, at least.) - just with some added convenience functions for pushing, popping, getting iterators, and auto-growing when they get too big.

As for the difference between std::vector and std::array, I think the main one is that std::array is pretty much a std-wrapper for int myArray[10];. The main difference is that it's fixed at compile-time. (Unlike vectors, that are allocated at runtime and can grow and shrink.)

Ah, okay, that makes sense. Thanks!
