binary - Cannot delete records from filing in C++ -


i coding little program university. want delete saved record of employee. when enter id of employee , delete it, seems have been deleted. when check record, still present there. can not figure out why. here code:

system("cls"); more = 'y'; while ((more == 'y')||(more == 'y')) {     faculty = fopen("employee.txt","rb+");     temp = fopen("temp.txt","wb+");     rewind (faculty);     cout<<"employee id: ";     cin>>xid;     while (fread(&em, empsize, 1, faculty) == 1)     {         if (xid != em.id)         {             fseek(temp, 0, seek_end);             fwrite(&em, empsize, 1, temp);         }         else              found=1;     }     fclose (temp);     fclose (faculty);     remove ("employee.txt");     rename ("temp.txt", "employee.txt");     if (found == 1)     {         //faculty = fopen("employee","rb+");         cout<<"delete record (y/n). ";         cin>>more;     }     else     {         system("cls");         cout<<"\n\n\t\t\t\""<<xid<<"\" id not exist.\n\t\t\tdelete                    record (y/n). ";         cin>>more;     }     if (more == 'n')     {         cout<<"\n\n\ttaking hr .. \n\t";         system("pause");         hr ();     } } break; 

before while loop need set value of found other 1. if delete record successfully, record deletion requests afterwards appear successful though weren't because found == 1 flag still set.
