plz help me with this error

Hi all!
can somebody please tell me what is wrong with the following code?
the header file:

Code:

---

#include <set>
template <typename T>
class professional_set
{
public:
        set<typename T> root;
        set<typename T>:: iterator it;
}

---

in .cpp file I have built an object like this:
professional_set <int> a;

when I compile it, it gives this error for the last line:
missing ';' before identifier 'it'
missing type specifier - int assumed. Note: C++ does not support default-int

what do I do now?

Your template class seems to be missing a trailing ;

Things in standard headers are in the std namespace.
Members of objects that depend on a template paramater rather than something concrete like int (I mean your iterator declaration), require you to help the compiler by prepending 'typename' to the declaration.
Unless you have something really convoluted (you don't), typename never goes within the angle brackets in a variable declaration. Just 'T' is enough.
