Assume that each of the following statements applies to the same program.
a.
Write a statement that opens file
oldmast.dat
for
input; use an ifstream object called
inOldMaster.
b.
Write a statement that opens file
trans.dat
for reading
and writing data to it; use fstream object
transFile
that can read data from the file trans.dat
as well as write data to it.
c.

accountNumber
, and a floating point data
dollarAmount

•
A default constructor.
•
Another constructor that has interest rate, years, and loan amount as its parameters.
•
A member function that returns the annual interest rate of this loan.
•

•
A member function that returns the amount of this loan.
•
A member function that sets a new annual interest rate to this loan.
•
A member function that sets a new number of years to this loan.
•
A member function that sets a new amount to this loan.
