How can I use boost::bind to bind a class member function?

Boost::bind(&player::play, &thePlayer) You need to use placeholders for the two arguments: boost::bind(&player::play, &thePlayer, _1, _2) The placeholders allow you to say "I'm only binding certain arguments; other arguments will be provided later.

And if you want create portable code - specify namespace of placeholders directly: boost::bind( &player::play, &thePlayer, ::_1, ::_2 ); // Placeholders of boost::bind are placed in global namespace.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
