Does it have to be in C++? Can you use external libraries?

I assume you mean the console screen.

First you have to figure out the screen width in characters. The old MS-DOS window was 80 characters wide, but that is no longer true. Once you know the screen width then the rest should be easy math. Something like this:

int main()
{
    std::string name = "Daniel";
    const int ScreenWidth = 80;
    while( name.length() > 0)
    {
        int center = (ScreenWidth-name.length())/2;
        cout << setw(center) << " " << name << '\n';
        name = name.substr(1);
    }
}
