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
