Project 2
Project 2-banking management system
- Create a console application for the banking management system.
- Create few classes namely Customer, Account, RBI (Base Class) and few derived classes (SBI, ICICI, PNB etc). Assume and implement required member variables and functions in each class.
- In every Bank there should be at least 2 types of account saving and current.
- Saving should give simple interest and Current should provide compound interest on deposited amount.
- In the current account the interest is compounded twice a year (on half yearly its compounded).
- For Every type of account at least 2 users will be there.
- On the running of the application it should ask which bank we want to access.
- Then what type of account you have.
- And then for which user account we want to access.
- Minimum amount for saving account is 2000/- and for current account is 5000/-
- And we can calculate the interest for any given time and total amount as well.
- Interest rates for saving will be 5% annually and for current it will be 8% annually.
- Before calculating interest it should ask the user for how many years you want to calculate it.
- Write code to calculate both types of interests as well for any of the users.
