     sizeof(contacts[num_contacts].fname));
     cout<<"Enter new email address: ";
     cin.getline(contacts[num_contacts].e_add,
     sizeof(contacts[num_contacts].e_add));
     cout<<"Enter number:";

     }while(command!=3);
     }

To edit you merely overwrite data usually (output the old data, input the new) to delete you usually remove the element by shifting all those after it back by one. I would suggest that an std::vector would be extremely useful in this situation.
