templates

[gizzmo]

Hi,
I have problem with compiling something like

template <class T>
T f(T a)
{
T::iterator it; // I need this iterator in the next line
//...some stuff...
return a;
}

Is this doable? T is a class (std::vector) with typedef std::vector::iterator iterator

Yes, though you may need a typename qualifier (I forget) and it would generate errors if instantiated with a class without that typedef.

Try using the typename keyword:

template <class T>
T f(T a)
{
typename T::iterator it; // I need this iterator in the next line
//...some stuff...
return a;
}
