C++ Exception Class

I have to write/fix this class for an exception in a tic tac toe prompt game, it has to throw an error whenever 0>x>8

Any of you brilliant motherfuckers want to help?

#ifndef illegalmoveexception
#define illegalmoveexception

#include <stdexcept>
#include <string>

using namespace std;
class illegalmoveexception : public illegal_move_exception
{
public:
    illegalmoveexception();
    : illegal_move_exception("invalid move")
   
};

You are an imbecile, In the first two cases they are working with incomplete theories in a still exploratory area of science, whereas you are dealing with something both simple and well understood. Religious people are wrong, because they choose to believe in fairy stories over providing any level of plausibility or falsifiability. And finally, what idea do atheist have that they can't implement a solution for? It seems to me the only thing that characterises Atheism is a lack of belief in a deity.
