Question

Here are requirements of a C code. I think it is not difficult for you because i have deleted some requirements. (I think it will be better if user can choose their identification once runned).

Please write in C and give some explains!

Overall description: Your team is employed by a bank to implement a system to manage the banking affairs. Customer specifications: The implementation of the banking system should be able to provide facilities to: • Register a new customer and store details such as name, address, telephone number, 6-digit personal identification number (PIN) number (security code for using the card) as well as some extra information (e.g., type of identification presented for joining the bank), etc. • Store and manage customer account information. Customers can have one or more accounts and each account is uniquely identifiable by an account number generated by the system.
