      {
                infile>>AppointmenList[currentSize].name;
                infile>>AppointmenList[currentSize].description;

        currentSize = currentSize -1;
        cout<<"\n\nRecords has been read from the file successfully!!!"<<endl;
        cin.get();
   
}
void editAppointmenRecords( )
{
        int editname;
        system("cls");  //clear screen
        cout<<"\nEnter person Name you want to Edit: ";
        cin>>editname;
        ifstream edfile("C:\\AppointmenRecords.txt");
        if(!edfile)          //return true if file is not opened

                cin.get();                     
          }

like finding and editing something from file.

Code:

---

void editAppointmenRecords( )
{
        int editname;
        system("cls");  //clear screen
        cout<<"\nEnter person Name you want to Edit: ";
        cin>>editname;
        ifstream edfile("C:\\AppointmenRecords.txt");
        if(!edfile)          //return true if file is not opened
          {  cout<<"\nFailed to open file!!!!\n";      //indicate program failed
                cin.get();                     
          }
}
