[resolved] ZeroMemory, for() loop, struct

[McCain]

Why won't this work?

typedef struct _GHOST
{
	int width;
	int height;
	int x;
	int y;
	int arrayx;
	int arrayy;
	int drctn;
	int speed;
}GHOST;

GHOST g_Ghost[3];

for(int i = 0; i < 3; i++);
	{
		ZeroMemory(&g_Ghost[i], sizeof(g_Ghost[i]));
		g_Ghost[i].width = 20;
		g_Ghost[i].height = 20;
		g_Ghost[i].arrayx = 18;
		g_Ghost[i].arrayy = 1;
		g_Ghost[i].x = 360;
		g_Ghost[i].y = 20;
		g_Ghost[i].drctn = 1;
		g_Ghost[i].speed = 4;
	}

It works if I replace the i with a 1.

Then I have 165 lines of code moving this ghost around the screen (mostly collision detection). All the code will be the same for all my ghost (I think I will have four ghosts), should I put all the 165 lines of code in one big for() loop or should I copy and paste the code four times. As this code is inside a game-loop it needs to be as fast as possible.
