   int account;
   double balance;
   //Allows user to enter an account number thatcannot be less than 1000 or greater than 9999
   cout<<"Please enter the accountnumber"<<endl;

   while((account < 1000) || (account >9999))

       cin>>balance;
   }   
   acctNum = account;
   acctBal = balance;
}

void BankAccounts::computeInterest()
{
   int year;
   cout<<"Please enter a term from 1 to40"<<endl;
   cin>>year;
   while(year > 40 || year < 1)
   {
       cout<<"You have chosenthe wrong number of years please try again"<<endl;
       cin>>year;
   }
   //calculates the balance with the interest rateaccording to the number of years
   acctBal = acctBal + year / 0.03;
}
void BankAccounts::displayAccount()
{
   cout<<"Account: "<<acctNum<<endl;
   cout<<"Balance: "<<acctBal<<endl;
}
//main function

int main()
{
   char ans;
   int i=0;
   BankAccounts account[10];

   do{
       account[i].enterAccountData();
       account[i].computeInterest();
       account[i].displayAccount();
       cout<<"Do you want toenter more data?(y/n)"<<endl;
       cin >> ans;
       i++;
   }while(ans == 'y');

   return 0;


Could someone help me make sure that the user is not allowed to usethe same account number for other accounts.

Also how do I make it so that after 10 accounts have been eneteredthe program quits?
