Since, a object of Package contains an item, why we are not storing reference of order in Package Class instead of orderid in the current code.
//current code
class Package {
private:
string packageId;
double packageSize;
string orderId;
public:
void pack();
};
//why it is not like this?
class Package {
private:
string packageId;
double packageSize;
Order order;
public:
void pack();
};
