String array problem? >_>;

QWERTYman (461)
With the following code, the '@' key set on line 80 does not appear.

Also, just noticed that the '@' key won't clear after you edit the string. >_>;

So what's your question?
QWERTYman (461)
My question is how I get the '@' key to at least display; editing the array doesn't seem to help.
Seraphimsan (954)
line 82, that should read

cout << (board[curr_y])[i];

or you need to have nested loops. I can't even get it to compile other wise.
QWERTYman (461)
Ah, so true.
EDIT: well, I'm displaying one row at a time.

Where is the comma operator separating each string?

std::string board[14] = {

                   "************",
                   "************",
                   "************",
                   "************",
                   "************",
                   "************",
                   "************",
                   "************",
                   "************",
                   "************",
                   "************",
                   "************",
                   "************",
                   "************"
};


Without the comma my array would seem like the first string is a huge one and the 13 other are just "";

Was that intended???

OH, DAMMIT!

Thanks!

It's the little syntactical errors that get me!

Nice proper use of an unnamed namespace. :)
