c++ - initializate template object -


i'm having little question... have template class, make bidimensional array:

template <typename t, unsigned p>  class mapa { private:     t **mat;     unsigned tam;  public:     mapa(t &dato);     mapa(const mapa& orig);     virtual ~mapa();     mapa<t, p> &operator=(const mapa<t, p> &orig);     t &operator()(unsigned i, unsigned j); };  template <class t, unsigned p> mapa<t, p>::mapa(t &dato) {     tam = p;     mat = new t**[tam];     (unsigned = 0; < p; i++) {         mat[i] = new t*[tam];         (unsigned j = 0; j < p; j++) {             mat[i][j] = dato;         }     } }  template <class t, unsigned p> mapa<t, p>::~mapa() {     (unsigned = 0; < tam; i++) {         delete mat[i];     }     delete mat; }  template <typename t, unsigned p> t &mapa<t, p>::operator ()(unsigned i, unsigned j) {     /*if (i < 0 || >= tam) {         throw errorderango("posición de memoria inexistente.");     }     if (j < 0 || j >= tam) {         throw errorderango("posición de memoria inexistente.");     }     if (k < 0 || k >= tam) {         throw errorderango("posición de memoria inexistente.");     }     return mat[i][j][k];*/  }  template <typename t, unsigned p> mapa<t, p> &mapa<t, p>::operator=(const mapa<t, p> &orig) {      tam = orig.tam;     mat = new t**[tam];     (unsigned = 0; < p; i++) {         mat[i] = new t*[tam];         (unsigned j = 0; j < p; j++) {             mat[i][j] = orig[i][j];         }     }     return mat; } 

i want use in next class:

class museo {     int sizestep;     mapa<objetomuseo*, 50> mapamuseo;  public:     museo();     ~museo();      void visualizar(); }; 

how should make constructor in museo.cpp initializate template object?

you can initialize fields using initialization lists.

museo::museo() : sizestep(0),    mapamuseo(???) { } 

where of course between ??? should add reference objectomuseo pointer constructor calls for.
