Zahlenwerte aus einem String "filtern"

[Gast]

geSTL'te Version:

void ExtractCoords( string text, map<char,double>& coords )
{
    string::reverse_iterator pos = text.rend();

    while ( ( pos = find_if(text.rbegin(), text.rend(), isAlpha) ) != text.rend() )
    {
        size_t dis = distance(pos,text.rend());

        coords[*pos] = lexical_cast<double>( text.substr(dis) );
        text.erase(dis-1);
    }
}
