I had a question regarding the way I am designing my particle system.
Right now I have a class P, which stores all the information about a particle such as speed, position, direction, type, etc. I also have a main file I will be drawing these particles, updating and instantiating them in. I want to create a list of these particles using the c++ std list library, so initially I did
std::list<P> listOfParticles;
in the main file. Here is the problem. By doing this I will essentially be forced to make my update and draw functions in the main file. I feel like this is bad practice, and that everything to do with the particle should be kept in one class, but I am unsure where to go from here in terms of best practice. Would it be a good idea to just create a list of particles in the class P where I am defining what a particle is? I feel like this isn't a smart idea though.. If anyone could guide me in the right direction I would really appreciate it.

No one is stopping you from putting declarations/definitions of class members in same/different .h/.cpp files.
EDIT:-
That's what I said, better it would be if you make this List a member of some other class where you would put all functions to manipulate this list.
