maybe you'd try something like this:




std::vector< std::string *> screen;
std::string vertical_line; vertical_line.resize(cols);
std::string empty_line; empty_line.resize(cols);...

Do you still have
c += pad
inside the "else"-clause?

In your first code-snippet it wasn't inside...

r.

try using:
cout << greeting.c_str()

enjoy,
r
