Making rooms out of grids?

Sweet the player can move around in 2 dimensions.

What if he could like go to different rooms and stuff? That would be killer.

Code:

int _tmain(int argc, _TCHAR* argv[])
{
	World Adventursaur;
	int enemy = 15;
	do
	{
		Adventursaur.you.move();
		enemy--;
		
	}
	while(enemy > 4);

	return 0;
}

So the encountering an enemy algorithm is a little shallow, but what If I want to Divide up the grids and organize between them?

Code:

	Point move()
	{
		direction = _getch();
		if (direction == 'w') y_location++;
		else if(direction == 'a') x_location--;
		else if(direction == 's') y_location--;
		else if(direction == 'd') x_location++;
		x_location = Bound(x_location, -10, 10);
		y_location = Bound(y_location, -10, 10);
		std::cout << x_location << ", " << y_location << std::endl;
		Point location;
		location.x = x_location;
		location.y = y_location;
		return location;
	}
