You could use this :
void experienced_Player( Player & p1, Player & p2 )
{
strength_t s1 = p1.GetStrength();
strength_t s2 = p2.GetStrength();
if( s1 > s2 )
else if( s1 < s2 )
else
}
Now you need to define a type that contains the strength, the strength_t, and write a method for the player object that returns its strength. You also need to add the code to print the messages.
