En fait le probleme ce que , je veux creer mon propre container a base de STL, avec l'algorithme que j'ai utilise on me donne des erreurs de compilation ( en Visual C++ 6.0). Aidez-moi a resourdre ce probleme.
Ca c'est l'agorithme utilise,
#include <iostream>
#include <list>
#include <string>
usingnamespace std;
template<class T>
class Ring {
list<T> lst;
public:
// Declaration necessary so the following
// 'friend' statement sees this 'iterator'
// instead of std::iterator:
class iterator;
friendclass iterator;
class iterator : public std::iterator<
std::bidirectional_iterator_tag,T,ptrdiff_t>{
list<T>::iterator it;
list<T>* r;
public:
// "typename" necessary to resolve nesting:
iterator(list<T>& lst,
consttypename list<T>::iterator& i)
: r(&lst), it(i) {}
booloperator==(const iterator& x) const {
return it == x.it;
}
booloperator!=(const iterator& x) const {
return !(*this == x);
}
list<T>::reference operator*() const {
return *it;
}
iterator& operator++() {
++it;
if(it == r->end())
it = r->begin();
return *this;
}
iterator operator++(int) {
iterator tmp = *this;
++*this;
return tmp;
}
iterator& operator--() {
if(it == r->begin())
it = r->end();
--it;
return *this;
}
iterator operator--(int) {
iterator tmp = *this;
--*this;
return tmp;
}
iterator insert(const T& x){
return iterator(*r, r->insert(it, x));
}
iterator erase() {
return iterator(*r, r->erase(it));
}
};
void push_back(const T& x) {
lst.push_back(x);
}
iterator begin() {
return iterator(lst, lst.begin());
}
int size() { return lst.size(); }
};
et voila les erreurs q'on me etourne:
