Problem Description
Polymorphism: Array Management
In this problem, you will create a program that reads the number and types of animals from standard input, stores Dog and Cat objects in an Animal-type array, utilizes polymorphism to call each object's makeSound() method, and displays the result to standard output.
Learning Objective: Understand how to dynamically manage different subclass objects using a parent class array
Overview
You have Dog and Cat classes that inherit from Animal class. Read animal types from input, store them in an Animal-type array, and output each animal's sound.
Specifications
- Animal class:
makeSound()method (empty implementation) - Dog class:
makeSound()outputs "Woof!" - Cat class:
makeSound()outputs "Meow!" - Read number N and each animal type ("Dog" or "Cat") from input
- Store corresponding objects in Animal-type array
- Call
makeSound()for all animals in loop
Input Format
N
type1
type2
...
typeN
- Line 1: Number of animals N
- Subsequent lines: Animal type for each ("Dog" or "Cat")
Output Format
Output each animal's sound on a separate line.
Sample Input/Output
Input:
2
Dog
Cat
Output:
