Kali ini ali ini Admin @feidodol akan membuat Program yang berfungsi mengolah data, adding data dan deleting data. Ikuti terus yaaa....

   cout<<"Deleted."<<endl;
  }
  else cout<<"Aborted."<<endl;
 }

}

void menu_view()
{
 cout<<"ITEM LIST "<<endl;
 cout<<setiosflags(ios::left);
 cout<<setw(5) << "ID"<<setw(30)<< "NAME"<<setw(10)<< "QTY"<<endl;
 for(int i= 0; i<item_count; i++)
 {
  TItem P = item[i];
  cout<<setw(5)<< P.id<<setw(30)<<P.name<<setw(10)<<P.qty<<endl;
 }
}

Inilah Hasilnya....
