Error when returning a structure pointer

Hi ,

  The following program gives error can any one solve this.

#include<iostream.h>

struct ab{
        int a;
};

template <class T>
class A{

                struct ab * ret_1();
        public:
                A();
                void disp();
                void ret();

};

template <class T>
void A<T>::ret(){

        struct ab* b;
        b=ret_1();

        return b;
}

template <class T>
struct ab * A<T>::ret_1(){

        struct ab* b;
        b=new (struct ab);

        return b;

}

template<class T>
A<T>::A(){

        cout << "A const" ;

}

template <class T>
void A<T>::disp(){
        cout << "disp" << endl;
}

int main(){

        A<int> a;

        a.disp();

        return 0;

}

This is just a sample program . I am trying to return a structure
pointer in a priviate method . but as the calss is template class
defining it is giveing me error . How could i rewite to remove the
error.
