Help.. C++

It’s been a while since I coded C++, so I am trying a website, very basic, but I have to start from somewhere. Anyway, here is the site: “http://www.unknowncheats.me/forum/counterstrike-global-offensive/129168-making-hacks-c.html”. I am currently on Challenge 1:2: “Same program as above but if the file already exists it greets the user with first name, last name and prints out how old they are and wishes them happy birthday if it is the user’s birthday.” Before I explain my problem, here is the source file: “http://hastebin.com/usobebicik.tex”. In the code I write “If the file exists, print what is in it”. The thing is the file is empty, and yet it prints out blanks and squares? I can’t tell really. If you could test the code for yourself. I’d like to know why it’s saying an empty file is bigger than 0 bytes. Thanks.
