Rational numbers (3) P53361
Using the same definition of the rational numbers as in problem P85696, write the functions
Rational sum(const Rational& a, const Rational& b);
Rational substraction(const Rational& a, const Rational& b);
Rational product(const Rational& a, const Rational& b);
Rational division(const Rational& a, const Rational& b);
that returns respectively the sum, the substraction, the product and the division of two rational numbers given, “normalized” according to the same convention that in the exercise .
Write also the procedure
void adds_one(Rational& r);
that adds an unit to the rational number r.
Precondition
The rational numbers a and b are correct and normalized. In the case of division, b ≠ 0.
Observation You only need to submit the required classes; your main program will be ignored. Strictly obey the type definitions of the statement.
