class my_iterator iterator_next(class my_iterator* i);
int iterator_get_key(class my_iterator* i);
double iterator_get_value(class my_iterator* i);
};
};
i tried to access the private variables of list_link through list_link(int,double,list_link*); constructor the compiler is giving me an error...
in the main file
1 2 3 4
sorted_list a;
a.insert(j,i);
in the implementation file sorted_list.cc
1 2 3 4 5 6 7 8 9 10 11 12 13
sorted_list::list_link::list_link(int key, double value,list_link* next=0)
{
this->key=key;
this->value=value;
this->next=next;
}
void sorted_list::insert(int key, double value)
{
sorted_list::list_link *temp,*current;
temp=new list_link(key,value);
temp->key;(it is giving me an error here saying that list is a private variable)
}
how can i access the private variables of an inner class...??

reading threw your posted sorce, the way i could see it done is have sorted_list have a public "get" method, and in that method have it call a "get" public method of list_link, that returns whatever values you want
main calls sorted_list_get_list_link()
sorted_list_get_list_link() calls list_link_get_stuff()
list_link_get_stuff() returns values you want
class sorted_list
{
private:
class list_link
{
private:
int key;
double value;
class list_link* next;
public:
list_link(int,double,list_link*);
~list_link();
};
class list_link* first;
public:
sorted_list();
~sorted_list();
void insert(int key, double value);
void remove(int key);
void copy();
};
hi i think that is what i have done..
the main function calls the public insert function void insert(int key, double value);
main function:
1 2 3 4
sorted_list a;
a.insert(j,i); calls the public insert function
implementation file sorted_list.cc
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
sorted_list::list_link::list_link(int key, double value,list_link* next=0)(gets called by the insert function)
{
this->key=key;
this->value=value;
this->next=next;
}
void sorted_list::insert(int key, double value)
{
sorted_list::list_link *temp,*current;
temp=new list_link(key,value); here the public constructor is getting called by the insert function
temp->key;(it is giving me an error here saying that list is a private variable)
}
Just make the variable public (the class is private so you can't access it from outside).
Or handle better the insert method (why you want to modify key?)
