Error C2270: Modifiers not allowed on nonmember functions

Solution
You have an error C2270 because your `busco` function is a free template function, it does not belong to a class. So `const` makes no sense on the signature : remove it.
If you intended this function to be a member function, place its definition at the point of declaration (I guess the `ABBImp` class), or prefix the declaration with the class name as you did for the `Recuperar` function.
Problem
I'm getting this error when compiling: error C2270: 'busco' : modifiers not allowed on nonmember functions I think I understand the reason but I don't know how to fix it, if I take the `const` out I get a C2662 error. Here is the code: ``` template <class T> class ABBImp: public ABB<T> { public: const T& Recuperar(const T &e) const ; private: NodoABB<T> * busco(NodoABB<T> * arbol,T &e) const; protected: NodoABB<T>* arbol; }; template <class T> //If I take this const out I get the other error I talked about NodoABB<T>* busco(NodoABB<T> * arbol,T &e)const{ if(a!=NULL){ if(arbol->dato==e) return arbol; else if (arbol->dato<e) return busco(arbol->der,e); else return busco(arbol->izq,e); }else{ return NULL; } } template <class T> const T& ABBImp<T>::Recuperar(const T &e) const{ NodoABB<T> * aux=busco(arbol,e); return aux->dato; } ``` Thanks!
