need help on 14.1 ... for 14.2 I have evrything but it says error on string in the rational cpp file... i have this ... progam is in c++

Section 4.2 4.1 (Use the Rational class) Write a program that computes the following summa- tion series using the Rational class: 98 99 99 100 *14.2 (Demonstrate the benefits of encapsulation) Rewrite the Rational class in Sec- tion 14.2 using a new internal representation for the numerator and denominator. Declare an array of two integers as follows: int r [2] Use r[0] to represent the numerator and r[1] to represent the denominator. The signatures of the functions in the Rational class are not changed, so a client
