#include 
#include 

Answer 1

The answer of Naveen is correct, I can add a suggestion: I use extensively typedefs and I'm waiting template typedef and "true type definition" typedef.

template 
class A
{
public:
    typedef typename std::vector >::iterator iterator;
    typedef std::pair MyPair;
    MyPair foo();
};

template 
typename A::MyPair A::foo()
{
    iterator aIter;
    return MyPair(aIter ,false);
}
