Define a class for rational numbers. A rational number is a number that can be represented as the quotient of two integers. For example, 21,43,264, and forth are all rational numbers. - Class name is Rational. - Represent rational numbers as two values of type int, one for the numerator and one for the denominator. Two constructors - Default constructor that initializes an object to 0 (that is, to 10 ) - Constructor with two parameters - Member functions for arithmetic operations (t,, *, /) - Member function for printing out the rational - Setters \& getters - Reduce the fraction addba+dc=bdad+bcsubstractbadc=bdadbc multiply badc=(bd)(ac) divide ba/dc=(bc)(ad) int nun1, denon1, nunz, denon2; cout e Enter nuserator and denoninator for r1;; cin >x nuni denonl; cout ee "Enter numerator and denoninator for I 2: : i cin nuaz denon2; Rational: ri(nunt, denon1); Aationat x (nun2, denon2); Rational sun =rl.add (r2) Ratiohal dif in i.subtract (r2); Do not change main function.
