game followed by int is illegal

Just doesn't work. I can't find a solution.

Visual studio 2019.

and in graphics.h i get an unexpected token struct.

Main.cpp

/*
    Main.cpp
    Entry point for the program.
*/

#include "game.h"

int main(int argc, const char* argv[]) {
	Game game;
	return 0;
}

graphics.h

#ifndef GRAPHICS_H
#define GRAPHICS_H

struct SDL_Window;
struct SDL_Renderer;

class Graphics {
public:
	Graphics();
	~Graphics();
private:
	SDL_Window* _window;
	SDL_Renderer* _renderer;
};

#endif

int main(int argc, char* args[])
{
Game game;
return 0;
}

Try this.
