        float xi, yi, x, y;
        clrscr();
        printf("Enter the sarting point x1 & y1\n");
        scanf("%d%d", &x1, &y1);
        printf("Enter the end point x2 & y2\n");
        scanf("%d%d", &x2, &y2);
        initgraph(&gd, &gm, "");
        cleardevice();
        dx = x2 - x1;
        dy = y2 - y1;
        if (abs(dx) > abs(dy))
                s = abs(dx); else
                s = abs(dy);
        xi = dx / (float) s;
        yi = dy / (float) s;
        x = x1;
        y = y1;
        putpixel(x1, y1, 4);
        for (m = 0; m < s; m++) {
                x += xi;
                y += yi;
