    the issue function is not working well instead of modifying the book record it is adding another book with a issue value 2
    can any one correct it
    Code:
    // **library management** //
// **library members can add,delete,modify and search book** // 
// **library members can operate users account** //
// **user can manage his record,issue and return a book** //
// **user can take only 1 book at a time** //
