c++ - Template class woes; Proper template signature? -

i implementing template class , not sure if have signatures correct. below i've included sample of code, showing couple of situations concerned about:

mymap.h:

---

#ifndef map_h #define map_h #include <iostream> #include <string>  using namespace std;  template <typename key, typename t> class map{ private:     struct elem {      };  public:      map();     // constructs empty map      map(const map &rhs);      ~map();      map& operator=(const map &rhs);      bool insert(key, t);      t& operator[](key);  };  template<typename key, typename t> ostream& operator<< (ostream&, const map<key, t>&);  #include "mymap.cpp"  #endif 

---

and .cpp file:

---

#include mymap.h #include <iostream> #include <string>  using namespace std;  //assingment operator template < typename key , typename t > map< key , t >& map< key , t >::operator=(const map &rhs){      //avoid self assignment     if( != &rhs ){           //snip     }      return *this; }   //insert, return true if successful. template < typename key , typename t > bool map< key , t >::insert(key, t){      //snip } 

---

as can see, , i'm sure aware, template signatures can pretty messy i've read. correct, or have blinding errors noticeable more practiced eye?

i know there million posts templates, i've read few guides them still cannot find on specific issue.

also, before inevitable "get rid of using namespace std" comments appear, include debugging , does end going away, promise:)

thanks!

edit: sorry confusion, seemed have missed important part of post... errors!

i have 5 of these, various line numbers:

mymap.cpp:41:1: error: ‘map’ not name type 

and equal number of:

expected initializer before ‘<’ token 

remove #include mymap.h mymap.cpp

then

#include "mymap.h" 

in test.cpp

and compile

g++ -g test.cpp 

for template classes, has in header.
