.11 Sprint 4:00 PM instructure-uploads.s3.amazonaws.com C 1 of 2 C.Object Oriented Programming Create a cless called Rational that represents a rational number. A rational number is any number that can be expressed os a ratio of two integers (a/b), with the denominater not equal to zere. 1) Use only two private member variables numeretor and denominator. Do not add any other ones 2) Create two constructors, one of which should be a default constructor 3) Add all necessary Get and Set functions 4) Create a private member helper function to store the result in the most reduced form·4/16 must be converted to 1/4 before it is stored in the object 5) If the denominator and the nominator are both negative numbers, the class removes the signs automatically. If the denominator is a negative number reverse the signs. This is done by the previous private helper function Examples: -3/-5 should be stored os 3/5 5/-7 should be stored as-5/7 6) Create a member function to add two Rational numbers (two objects of the class). 7) Add three more similar functions to subtract, multiply, and divide two Rational numbers (two object of the rational class) 8) Create a function to print the rational number in the form of a/ (1/4) 9) Add another function to print the number in the form of a floating point (25) 10) Remember, all functions are member functions, such as add) and multiply) In order to test your class in your main function, prompt the user for numerafor and the denominator for your first object. Repeat the prompt for the second object. Perform all mathematical operations by calling the functions. Print the two rational numbers in both print forms (a/b) and as a fleating point. Then, print the result of the calculations in both forms. Make sure you label all numbers printed, for instance Your first rational number is: 3/2 which is 1.5 Your second number is 5/2 which is 25, The sum of the numbers is 4/1or 4.00 Output the rest of the result the same way Nnte thnt in the nhave nmnle 3/2 5/2 R/2 r rinee etore the frnrtinn in theExplanation / Answer
