It doesn't appear to be question, I think it is the G20 solution to the banking crisis. It's not like it could be any more ineffective than the current proposals......

Yup, that'll get the economy back on an even keel, no toxic debt, sub prime. Just straightforward money in - money out. Sorted.

hello,

I have the same question but its not my assignment.I am doing it for my personal interest.The problem in doing this is that,I want to show the account details from account number,but how to assign account number to each account holder?My program runs only for single input not for an array.I have used classes in it.Can anyone tell me how to assign account number to each account holder if the user open an account?Is inheritance necessary for this problem?

No inheritance needed. You want some type of Bank class that can CreateAccount()'s and CloseAccount()'s for customers. The BankAccount that has customer information will also include the accountNumber, and the Bank can store a map of BankAccount's keyed by accountNumber.

Thanx medievalelks problem done but only for single account.If I create two or more accounts,then function(details) in my code show the last entry.I know array should be used here but how?I dont want to use linked list.Here is my code for single account.

Code:

# include<iostream>
# include<string.h>

using namespace std;


int choice;
class bank{
      
      private:
              int age,balance,accountnumber,amount;
              string name,occupation,address;

        static int account;      

      public:
             int accountno;
             bank(){};
             ~bank(){};
             void open();
             void deposit();
             void withdraw();
             void details();
             
             
             
};   


                      
           
 int bank::account=1000;          
           
             void bank::open()
             {
                  cout<<"Enter name\n";

I would rename your bank class to account, since that's really what it is. Then, create the bank class to hold multiple accounts, using a std::map as the container (not an array).

The std::string key of the map could be account number:

Code:

std::map<std::string, boost::shared_ptr<account> > accounts;

If you don't want to download Boost and learn about shared_ptr's just yet, just use a raw pointer:

Code:

std::map<std::string, account *> accounts;

I'll let you Google std::map (or use the link in my other post :-)).
