    string padding

    I'm getting this error
    Game.cpp:645: warning: cannot pass objects of non-POD type ‘struct std::string’ through ‘...’; call will abort at runtime
    Game.cpp:645: warning: format ‘%*s’ expects type ‘char*’, but argument 3 has type ‘int’

    with this code:
    string boardTimeholder=boardTime->toString();
    And my toString returns a string. I'm really confused.

    Use %s to print out a c-string (char*). If you want to print an std::string, either use iostream or you can get the c string equivalent with the c_str() method of string.
    I copied it from the last program in which I passed a parameter, which would have been pre-1989 I guess. - esbo
