Constant Pointers
constant pointer is a pointer that cannot change the address its holding. In other words, we can say that once a constant pointer points to a variable then it cannot point to any other variable.
example declaration:
int * const ptr;

Pointer to Constant
These type of pointers can change the address they point to but cannot change the value kept at those address.
example of definition could be :
const int* ptr;
