Rewrite this code using inheritance. You should have a Pet class with subclasses for Dog, Cat, and Bird. Variables should be associated with the appropriate classes, defined as private when appropriate, and have appropriate functions to access the variables. Rewrite the printDescription function as a virtual function. There should no longer be the need for a switch statement or a type variable. Write a main function that creates a vector or array of pets that includes at least one bird, one dog, and one cat, and then loops through and outputs a description of each one
