const object pointer vs. const pointer

1.const is located on the left of the Modifier object; on the right side, the modifier pointer

2.const only when the object is decorated, the const object's pointer itself can be changed, that is, the pointer address can be changed (pointing to other objects), if the const modifier pointer, the pointer itself cannot be changed, but does not qualify the value of the object referred to

1I=0;2 Const int*ip=&i;//Qualifying Object I only3 int Const*ip=&i;//Qualifying Object I only4 int*Constip=&i;//limit pointer IP only5 Const int*ConstIp=&i//Defines both the object I and the pointer IP
