Dear progga 
U are right. But my doubt is : when i run gdb and execute p ptr either
just after or before printf, pbc has been displayed. I'm getting
segmentation fault only at the end, it seems, because when i run
./a.out  "pbc is not displayed" but prompted segmentation fault error.
why is it so? How does segmentation fault raises, though
pointer-pointing contents has been changed & even displayed using gdb. i
am interested to know the internals. 
Thanq for ur interest. 
Regards 
Krishna Mohan

     Since ptr points to read-only mem, changing ptr[0] does not seem to be a very
    wise idea.
