Demonstrating Inheritance in C# - The Animal Class

The Animal class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace InheritanceAnimals
{
    public class Animal
    {
        //fields
        private bool legs;
        private bool wings;

        //properties
        public bool Legs
        {
            get { return legs; }
            set { legs = value; }
        }
        public bool Wings
        {
            get { return wings; }
            set { wings = value; }
        }

        //constructors

        public Animal(bool _legs, bool _wings)
        {
            this.legs = _legs;
            this.wings = _wings;
        }

        //methods
        public virtual string eat()
        {
            return " unknown";
        }

        public virtual string hair()
        {

        }

        public virtual string sound()
        {

        }

    }
}

The Bat class:

using System;

        public string take_off()
        {
            return "launches from the tree";
        }

        public string land()
        {

And finally, the GUI form sourcecode:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace InheritanceAnimals

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btnShow_Click(object sender, EventArgs e)
        {
            Snake snake = new Snake();
            Monkey monkey = new Monkey();
            Bat bat = new Bat();
            Hawk hawk = new Hawk();

            string myresults = "";

            myresults = "Snake (" + snake.Legs + " " + snake.Wings + ") eats " + snake.eat() + ", hair = " + snake.hair() + ", sound = " + snake.sound() + ", moves = " + snake.movement() +"\n\n";
