if (fPlayers[i].getName() == "Computer")
This line makes no sense; fPlayers[i] is a pointer, and pointers do not have member functions. I suspect you mean to call the member function of what that pointer actually points to. Try
At the point in the program you're trying to use fPlayers, it does not exist. If this is inside a function, then you need a way to pass fPlayers to that function, or to make fPlayers some kind of hideous global variable, or provide some way that the function can fetch fPlayers.
