Consider this declaration of the class Fraction: class Fraction { private: int numerator, denominator; public: Fraction operator+(const Fraction & frac2); Fraction & setNumerator(int numer); Fraction & setDenominator(int denom); }; a. Why is there only one parameter, frac2, used with operator+, even though addition has two operands? b. Write the operator: Fraction Fraction::operator+ (Fraction frac2){ } c. Write setNumerator() and setDenominator() as cascading functions: Fraction & Fraction::setNumerator(int numer) { } Fraction & Fraction::setDenominator(int denom) { } d. Assign the fractions frac1...
