C++ Project on Banking System

Banking
IN THIS PROJECT YOU CAN KEEP RECORD OF DAILY BANKING TRANSACTIONS.
THIS PROGRAMME IS CAPABLE OF HOLDING ANY NO. OF ACCOUNTS.
IN FIRST OPTION YOU CAN SEE ACCOUNT OF A PARTICULAR PERSON BY GIVING SIMPLY ACCOUNT NO. OF THAT PERSON.
IN SECOND OPTION YOUN CAN SEE THE LIST OF ALL ACCOUNTS.
THROUGH THIRD OPTION YOU CAN DO BANKING TRANSACTIONS ( DEPOSIT / WITHDRAW )
IN FOURTH OPTION YOU CAN OPEN NEW ACCOUNT. 
NOTE: OPENING AMOUNT SHOULD NOT LESS THAN Rs.500/-. 
IN THE FIFTH OPTION YOU CAN MODIFY OR DELETE ANY ACCOUNT.
AND LAST OPTION IS QUIT (EXIT TO DOS).
