1. Define your own namespace CreatingAndUsingObjects and place in it two classes Cat and Sequence, which we used in the examples of the current chapter. Define one more namespace and make a class, which calls the classes Cat and Sequence, in it.
2. Write a program which creates 10 objects of type Cat, gives them names CatN, where N is a unique serial number of the object, and in the end call the method SayMiau() for each of them. For the implementation use the namespace CreatingAndUsingObjects.
