How to save array of struct with vector in binary C++ -

i need save array of struct in binary file. there problem! have 3d array of vector in struct! struct :

struct state {     vector<bool> ***value;     vector<int> ***rfcclb2bits;     state()     {       new3darray(value , 60 , 100 , 2);       new3darray(rfcclb2bits , 60 , 100 , 2);     }  }; 

and may want see new3darray function :

template <class t> void new3darray(t ***&u3d, int nx , int ny , int nz) {     u3d = new t ** [nx];     if (null == u3d)     {       cout <<"erro3"<<endl;     }     else     {         (int = 0; < nx; i++)         {             u3d[i] = new t *[ny];             if (null == u3d[i])             {                 cout <<"erro4"<<endl;             }             else             {                 (int j = 0; j < ny; j++)                 {                     u3d[i][j] = new t [nz];                     if (null == u3d[i][j])                     {                         cout <<"erro5"<<endl;                     }                 }             }         }     } } 

at last code saving , loading :

int main() {     state *states;     int k ;     cin >> k;     states = new state[k];      ...      string location = "save1.bin";     ofstream fs(location, std::ios::out | std::ios::binary | std::ios::app);     fs.write(reinterpret_cast<const char *>(states), sizeof(states));     fs.close();      ...      ifstream file (location, ios::in|ios::binary|ios::ate);     if (file.is_open())     {         file.seekg (0, ios::beg);         file.read ((char*)&states, sizeof(states));         file.close();     }      ... } 

but didnt work! must do?
