{
      char filename [ FILENAME_MAX ];
      sprintf(filename, "%d.txt", roomnum);
      char ch2;
      ifstream fin(filename );               // i want to use ios class's and ios::noreplace but i get error ?
      if (fin.bad()) cout<<"An Error has happend on opening the file";
      while (fin.get(ch2))
      cout<<ch2;
      cout<<"\n";
      fin.close();
}


int roomsave(string roomname,string roomdisc,int roomnum)
{
      char filename [ FILENAME_MAX ];
      sprintf(filename, "%d.txt", roomnum);
      
      ofstream fout(filename);
      if (fout.bad()) cout<<"An Error has happend saving the file";
      fout<<endl<<roomname<<endl<<endl;
      fout<<roomdisc;
      fout.close();

int roomedit(int roomnum)
{
    string roomname, roomdisc;

    cout<<"Room Name: ";             // how do i use getline on these two cin lines 
    cin>>roomname;                   // when i have used them the program shows both cout on same line and only takes one entry
    cout<<"Room Discription: ";      // also i would like to know how i save these to a specific a line in file
    cin>>roomdisc;                   
    
    roomsave(roomname, roomdisc, roomnum);
