Pointer to constant: If pointer is pointing to constant
variable is caller pointer to constant. We can not change
the value of that constant.
const int constVariable = 6;
int *ptrConstVar = &constVariable;
Constant Pointer: We declare a pointer as constant. We can
change the content pointed by pointer. But we can not do any
airthmatic operation on the pointer like increment or decrement.
int localVariable =10;
const int *p = &localVariable;
we can not do p++ or p--;
