2. Implement operator overloading. Operator Overloading a) Implement one unary operator overload functions (-,+, !). b) Implement any two arithmetic operator overload functions (+,-,*,/,%). c) Implement any two relational operator overload functions (==, !=,>,<=). d) Implement the insertion operator overload function (<<). e) Implement the extraction operator overload function (>>). f) Implement the subscript operator overload function ([]). Make sure that each function is optimally overloaded for its purpose. (pick between member, non-member, friend as appropriate) Notes Add Rational Numbers Given a/b + c/d: Step 1: Find the LCM of b and d. Step 2: Create a new Rational Number: ((a* (LCM/b) + (c* (LCM/d)) / LCM. Step 3: Reduce the new Rational Number from step 2. Step 4: Return the new Rational Number. Subtract Rational Numbers Given a/b - c/d: Step 1: Find the LCM of b and d. Step 2: Create a new Rational Number: ((a* (LCM/b) (c* (LCM/d) ) / LCM. Step 3: Reduce the new Rational Number from step 2. Step 4: Return the new Rational Number. Multiply Rational Numbers Given a/b * c/d: Step 1: Create a new Rational Number: (a*c) / (b*d). Step 2: Reduce the new Rational Number from step 1. Step 3: Return the new Rational Number. Divide Rational Numbers Given a/b / c/d: Step 1: Create a new Rational Number: (a*d) / (b*c). Step 2: Reduce the new Rational Number from step 1. Step 3: Return the new Rational Number. Compare Rational Numbers: greater than Determine if a/b > c/d: Step 1: Find the LCM of b and d. Step 2: If (a* (LCM/b) > (c* (LCM/d) return true, otherwise false. Compare Rational Numbers: less than Determine if a/b < c/d: Step 1: Find the LCM of b and d. Step 2: If (a* (LCM/b) < (c* (LCM/d) return true, otherwise false.
