        int i, err, x, y, maxy;

        /* initialize graphics system */
        initgraph(&graphicDriver, &graphicMode, "C:/TURBOC3/BGI");
        err = graphresult();

        if (err != grOk) {
                /* error occurred */
                printf("Graphic Error: %s\n",

        x = y = 0;

        /* maximum y value */
        maxy = getmaxy();

        /* setting the current line style */
        setlinestyle(SOLID_LINE, 1, THICK_WIDTH);

        for (i = 0; i < getmaxx(); i = i + 25) {
                /*
                 * draws vertical line from
                 * start to end of screen
                 */
                line(x + i, y, x + i, maxy);

                /* sleep for 100 milliseconds */
