Question

Define a class called CUSTOMER with the following members name_of_the_customer type_of_loan number_of_months principal_amount EMI There are 3 member functions. First one to set the value for name_of_the_customer, number_of_months, principal_amount and type_of_loan. Second one to print all the data members. Third function to calculate EMI and it is calculated as follows. If type_of_loan is “bike” then monthly interest rate is 9.2%. If type_of_loan is “Home” then monthly interest rate is 7.35%.
