!!!... Election Voting Software ...!!!

Well this is the project which i made in 12th , 3 yrs back. It took me 2 mnths to complete this project but in the end all was running fine. This Program wen runned (ignore 8 warnings ) in Turbo C++ asks for a password which i have initally set to "divakar" and u can change it . After that it displays a menu. Since their are no database of candidates and voters initally so you have to first edit and enter the records of candidates and voters and den start voting. Remember this " for evry time u run the program u have enter the details of candidates n voters and this database is temporary..".. for any problems contact..
