templates question

[Babis Haldas]

Hi There

In the follow code the line
list<A<T> >::iterator i; doesnt compile (missing ; before i)
How i should define the iterator ?

#include <iostream>
#include <list>

using namespace std;

template <typename T>
struct A {
T x;
};

template <typename T>
struct B {
list<A<T> > a;
list<A<T> >::iterator i;
};

int main()
{
B<int> b;
}

Name list<A<T> >::iterator depends on template parameter (T), so you
must use keyword typename:
typename list<A<T> >::iterator i;
