yes... pointers can made const. The compiler will tell you if you attempt to change const pointer, which adds a great deal of safety.
When using const with pointers, you have two options : const can be applied to what the pointer is pointing to, or the const can be applied to the address stored in the pointer itself.

Yes pointers can be made const pointers as well.
const char *const cpc
is a definition to declare a const character pointer.
Of course, there are special initialization and assignment rules that one needs to follow for these const pointers to work. I would suggest referring to Stroustrup/Lippman for further details
int *const pci
is a definition to declare a const integer pointer where the content of the pointer can be modified, but the pointer itself can't.
