Here's another way that will ensure the text is centered within a given width and is padded left and right with spaces.

std::string center(const std::string s, const int w) {
    std::stringstream ss, spaces;
    int pad = w - s.size();                  // count excess room to pad
    for(int i=0; i0 && pad%2!=0)                    // if pad odd #, add 1 more space
        ss << " ";
    return ss.str();
}

This could be written more elgantly or concisely.
