Classes, constructor and pointer class members
- by pocoa
I'm a bit confused about the object references. Please check the examples below:
class ListHandler {
public:
ListHandler(vector<int> &list);
private:
vector<int> list;
}
ListHandler::ListHandler(vector<int> &list) {
this->list = list;
}
Here I would be wasting memory right? So the right one would be:
class ListHandler {
public:
ListHandler(vector<int>* list);
private:
vector<int>* list;
}
ListHandler::ListHandler(vector<int>* list) {
this->list = list;
}
ListHandler::~ListHandler() {
delete list;
}
