Constant pointer:
-----------------
If you have a value in your program and it should not
change, or if you have a pointer and you don't want it to be
pointed to a different value, you should make it a constant
with the const keyword.

Answer / srsabariselvan
constant Pointer:
we can't modify the value of pointer.i.e.,value of
pointer is constant.
Declaration:
int i=2,j;
int const *p;
p=&i;
p=&j;
Pointer Constant:
in case of Pointer constant, we can't modify the address of
pointer.i.e,address stored in pointer is constant.
This must be intialized
Declaration:
int i=2;
int *const p=&i;
*p=4;
