[HELP] Help me get started hacking pleaseee

Hehea so lets see I hate to leach of other's work since it makes me feal like ive done nothing but waste my own time creating another hack with the same exact code as all the other leachers running behind maybe a slightly changed up menu.

So I know the first thing would be to learn c++ which Im slowly doing but I have a few questions that I havent been able to answer for myself reading around here. First the addies.... Im not quite sure how you guys find them.... Im guessing theyre just pointers to where data is stored for fog etc etc but still dont know how you find them. Second the pushtoconsole thing.... is that basically a function that pushes commands to combat arms or does it push values to where the adresses point? Im not sure if I even have the right idea here but bear with me.

Then last of all does this mean if hacks are patched most of the time the only thing that has to be updates are addies?
Thanks for any help in advance
