Hello, I am wondering if you can help me with my homework assignment.
I am trying to create a program that runs in bank teller machine.  From this teller if existing customer, you can withdraw, deposit and check balances,  If not, you can become a new customer.  When someone becomes a customer, an account number that identifies this particular cliet is generated.  How can I write a method to generate this account number?   The only information I am requesting from the new client is first name, lastname, telephone, and initial desposit.
Thank you.

simply....just put the numbe generated in the vector, during next number generation, check for it in the vector, or else,generate new number....but careful, u may not be sure that u will always generate unique number or it will take more time, since it can generate the same number if some 1000 numbers or more is in the vector and each time it makes a check and lot of resources will be wasted
