This will force the user to enter 1001 chars. I don't think that is what you want.
Line 48 and 49 doesn't do anything.
And this will not work int numDig1 = sizeof(*Number1)/sizeof(char);*Number1 is a char and sizeof(char) is always 1 so numDig1 (and numDig2) is always 1.
Uh, thank you, I totally forgot about the two lines / 48 & 49 / .... :D
I modified the two whiles, so when they meet + or ? - break.
Should I use atoi to get the length ?
Also is there a way we can communicate faster ?
Thanks again ;) !
