Vertex Array

I have problem in rendering multiple similar shape (circle).
This is my code


void initCircleVertices(float r)
{
	float degree = 0;
	unsigned int ctr = 0;

	for(int xi = -320; xi < 320; xi+= 2*r)
	{
		for(int yi = 240; yi > -240; yi-= 2*r)
		{
			for(int i = 0; i < 360; ++i)
			{
				vertices.push_back(xi + r * cos(float(degree)));
				vertices.push_back(yi + r * sin(float(degree)));
				vertices.push_back(-8);
				
				indices.push_back(i+ctr);
				++degree;
			}
			ctr += 360;
			degree = 0;
		}
	}
}


void drawCircles()
{
	unsigned int i = 0;
	for(i = 0; i < indices.size()/360; ++i) 
	{
		glEnableClientState(GL_VERTEX_ARRAY);
		glVertexPointer(3, GL_FLOAT, 0, &vertices[i*360]);
		glDrawElements(GL_LINE_LOOP, 360, GL_UNSIGNED_INT, &indices[i*360]);
		glDisableClientState(GL_VERTEX_ARRAY);
	}
}



resulting in this image. How to render it normally?
