Four doubles are read from input, where the first two doubles are the kilograms and grams of weight1 and the second two doubles are the kilograms and grams of weight2. Define two functions to overload the + operator. The first function overloads the + operator to add a mass and a double representing the number of kilograms. The second function overloads the + operator to add two masses. Ex: If the input is 14.0299.55.0162.5, then the output is: 14 kilograms, 299.5 grams 5 kilograms Sum: 19 kilograms, 299.5 grams 14 kilograms, 299.5 grams 5 kilograms, 162.5 grams Sum: 19 kilograms, 462 grams Note: The sum of a mass and a double representing the number of kilograms is: - the sum of the number of kilograms and the double - the number of grams is unchanged Note: The sum of two masses is: - the sum of the number of kilograms - the sum of the number of grams double kilograms2; double grams2; cin >> kilograms1; cin > grams1; cin > kilograms2; cin > grams2; Weight weight1(kilograms1, grams1); Weight weight2(kilograms2, grams2); Weight sum1 = weight1 + kilograms2; Weight sum2 = weight1 + weight2; weight1.
