uggg....oh man i will probably figure it out before anybody respods but just incase i don't here's my problem. it's soo anoying

i'm asking the user to enter n (notice small) if they don't want the program to continue, but when they press 'N' (notice capital) my loop just continues. so i tried fixing it with this statement:

while(ch!='n' || ch!='N')

but now the problem is that the loop continues if the user enters n or N. not what i want. i want the program to exit when the user enters n or N. any thoughts on this would be greatly appreciated. thx
