// ==============================================================================
// Here is the core of the excercise
//
// This function called battle() receives two SuperHeros polymorphically.
// so that it may really be passed all sorts of sub-classes of the SuperHero class
//
// Many of the methods it calls are virtual and will hence be overridden
//

void battle( SuperHero& one, SuperHero& two )
{
  // This is the most trivial way to decide the outcome
  // Realy you would use a random number mechanism, but we wont complicate here

  // Note that crucially any overriden virtual power() methods will be called.

  if( one.power() > two.power() )
  {
    std::cout << one.announce() << " vanquishes " << two.announce() <<std::endl ;
    one.fightResult( true ) ;
    two.fightResult( false ) ;
  }
  else
  {
    std::cout << two.announce() << " vanquishes " << one.announce() <<std::endl ;
    one.fightResult( false ) ;
    two.fightResult( true ) ;
  }
}
