           main()
           {
               int maxx, maxy;
               int xcenter, ycenter, adjx;
               int len;
               char *tst = "This string is centered.";

               initgraph(&gdriver,&gmode,"");
               maxx = getmaxx();
               maxy = getmaxy();
               xcenter = maxx/2;
               ycenter = maxy/2;
               len = strlen(tst)*8;
               adjx = xcenter - len/2;
               outtextxy(adjx,ycenter,tst);
               getch();
               closegraph();
