    The problem is in the use of the post-increment operator. Don't use it until you are completely familiar with its use because it will confuse you...............exactly as it just has done.

    in *(cstr1+y)
    here the adress is incremented by the value of y (i.e 1,2,3,4) and the memory location in the adress is displayed
    but in (*cstr1)++
    here the adress is incremented by the value of y (i.e 1,1,1,1) and the memory location in the adress is displayed
    so there is a change in adress location that why so confusing..................
