Program wont change array value - arrays

Question

(Win32 console app) Ok so i know its a bit to look at, but ive added as many helpful comments that i could think of, im sort of new to coding so if this is a quick fix i apologize for taking your time, ive searched high and low and cant figure this out. So, it prompts the user for a name, that works, then for a race, that works, but under the display function, it fails to show the updated stats (updated by which race you choose). although sometimes it will work with the hp/maxHP but not att nor def. im not sure if its something to do with the scope or what, ive tried all i know :/ thanks for your time and help :)

Answer 1

You are using the wrong index for def. It should be 4
Def: " << stats[5].
