You are overflowing the buffer and stomping on memory you don't own.
Don't do that!!! Really bad things can happen. You are just unlucky
that it seems to have worked so far.

In today's C++, you should never use char arrays to manipulate strings.
Doing so can be really tedious, and it's just too easy to forget how big
your buffer is and write past the end of it. Always use a string class
instead. I prefer std::string, but any class, even CString, is better
than using char arrays.
