Create a class hierarchy to classify numeric values with interface Number. Define subclasses WholeNumber and RealNumber. WholeNumber has subclasses EvenNumber and OddNumber. For each integer in the inclusive range 0 to 10 descending, create a new instance of the appropriate number subclass and add it to an STL structure that supports efficient insertion and retrieval. Efficiently iterate your container and print the numeric value and whether the object is an EvenNumber, OddNumber, or RealNumber for each object. Efficiently locate the object with the smallest value not less than 9.5 and print its value. All your interactions with objects should be through the Number interface.
