/*
write a c++ program to create a class FDA accout containing member as:
-fdno
-name
-amt
-interest rate
-maturity amt
-number of months
use parameterised constructor to set appropiate details where interest rate
should be a default argument. calculate maturity amt using interest rate and
display all the details.
