C ++创建一个指向const对象的指针数组

Question

I'm trying to make a non-constant array of non-constant pointers to constant objects. The idea is that I should be able to change what the pointers in the array point to, but what they point to is a constant object.

I'm having problem defining this array (it's an array of pointers to objects of type Person - a custom class). I'm currently declaring the array like so:

Person* people[10];

Also that's not explicitly saying that the pointers point to const Persons. So when I do something like this:

people[i] = &p;

where p is a reference to an object of type const Person , it fails.

Answer 1

When in doubt ... use typedef (because it's explicit, adds more specialized semantics and avoids the confusion completely):

typedef const Person* PersonCPtr;
PersonCPtr people[10];
