C++ header file using STL

[mailarchis]

I am trying to write a header file in C++.It has some classes which make use of C++ STL.Say for example the following code

foo.h

template <class key,class val> class d_array {
	
	public :
	map <key,val> h;
	val &operator[](key k);
	val &operator[](map <key,val>::iterator itr);
	void clear();
	int defined(key k);
	void undefine(key k);
};

N.B I have included the required header files and namespace.
Am not sure how to write the operator definition for [] in the corresponding C++ file.

Do you want something like this

template <class key,class val> 
class d_array 
{
	public :
	map <key,val> h;
	val &operator[](key k);
	val &operator[](map <key, val> mp);
	void clear();
	int defined(key k);
	void undefine(key k);
};

template<class key,class val>
val& d_array<key, val>::operator [](key k)
{

}

template<class key,class val>
val& d_array<key, val>::operator[](map<key,val> mp)
{
	map<key, val>::iterator it = mp.begin();
}

int main(int argc, char** argv[])
{	
	return 0;
}

Please check and let me know...Also if I'm wrong please do comment
Thankx
