Using C sharp windows form Create a struct called Rational for performing arithmetic with fractions. Write an app to test your class. Use integer variables to represent the private variables of the struct-the numerator and the denominator. Provide a constructor that enables an object of this struct to be initialized when it's declared. The constructor should store the fraction in reduced form. The fraction 2/4 is equivalent to 1/2 and would be stored in the object as 1 in the numerator and 2 in the denominator. Provide public methods that perform each of the following operations (all calculation results should be stored in a reduced form): Add two Rational numbers. Subtract two Rational numbers. Multiply two Rational numbers. and Divide two Rational numbers
