    The following is
    what I have done , but no window is displayed on the screen.

Your code is rather strange looking.

    scrn = 1;
    scn = XScreenOfDisplay(dp, scrn);
    parent = XRootWindow(dp,0);

Why are you getting screen 1, but then getting zero's root window?

    XMapwindow(dp, parent);    

There is no point in mapping the root window, it's already mapped.
Also, this won't even link (it should be XMapWindow).

Except for that, your program does display a window on the screen,
so I don't know what your problem is.
