In a bank, different customers having saving account. Some customers may have taken a loan from the bank. So bank always maintains information about bank depositors and borrowers. Design a Base class Customer (name, phone-number).Derive a class Depositor(accno, balance) from Customer. Again derive a class Borrower (loan-no, loan-amt) from Depositor. Write necessary member functions to read and display the details of ‘n’ customers.
