Thread: micrososoft foundation class quick question

Why don't I get an error here? There is no where in the code I initialise the buffer array. Should there not be an error on LINE 22?

Code:

double point[6][3]; 
	double buffer[6][3];

	//p1
	point[0][0] = 300;  point[0][1] = 50;  point[0][2] = 0;
	//p2
	point[1][0] = 150; point[1][1] = 50; point[1][2] = 0;
	//p3
	point[2][0] = 260;  point[2][1] = 150; point[2][2] = 0;
	//p4
	point[3][0] = 250; point[3][1] = 200; point[3][2] = 0;
	//p5
	point[4][0] = 160; point[4][1] = 300; point[4][2] = 0;
	//p6
	point[5][0] = 300; point[5][1] = 300; point[5][2] = 0;

...


for (int j=1;j<5;j++)
		{
			pDC->MoveTo(buffer[j][0], buffer[j][1]);
			pDC->LineTo(point[j][0], point[j][1]);
			buffer[j][0] = point[j][0]; 
			buffer[j][1] = point[j][1];
		}

What error were you expecting?

If you turn up the warning level on the compiler, you might get a "use before initialisation" message.
