class Node{

};
[C++] readonly class members?
Author
why can't one simply do this and expects for it to work:
see the last 2 members: how can i make them read-only?
note that
int getData() const { return data; };
int *getNext() const { return next; };
does not work.

see the last 2 members: how can i make them read-only?
note that
int getData() const { return data; };

does not work.
const int getData() { return data; };
const int *getNext() { return next; };
will make them return a "read-only" int and a pointer to a "read-only" int, respectively. That doesn't make the member functions themselves read-only. Member functions are already read-only.
The following Works HereTM:
Please define 1° what you mean by read-only (since, by definition, functions returning non-references are read-only members) and 2° what you mean by not working.
int getData() const { return data; } Node *getNext() const { return next; }Please define 1° what you mean by read-only (since, by definition, functions returning non-references are read-only members) and 2° what you mean by not working.
