lab6b (ASLR) | Newlines are not being removed from user input fields

Newlines are not being removed from any user input (both for username and password). Therefore, unless they are both 32 bytes long, they will never match the actual fields because of the '\n' difference.

I suggest adding this after both fgets calls: readbuff[strcspn(readbuff, "\n")] = 0;
