Description

Problems for exercises and homework for the “C# OOP” course @ SoftUni”.
You can check your solutions here: https://judge.softuni.bg/Contests/1499/Inheritance-Lab
Part I: Inheritance
1. Single Inheritance
NOTE: You need a public StartUp class with the namespace Farm. Create two classes named Animal and Dog.
Animal with a single public method Eat() that prints: “eating…”
Dog with a single public method Bark() that prints: “barking…” Dog should inherit from Animal.

Hints
Use the : operator to build a hierarchy
2. Multiple Inheritance
NOTE: You need a public StartUp class with the namespace Farm. Create three classes named Animal, Dog and Puppy.
Animal with a single public method Eat() that prints: “eating…”
Dog with a single public method Bark() that prints: “barking…”
Puppy with a single public method Weep() that prints: “weeping…” Dog should inherit from Animal. Puppy should inherit from Dog.

3. Hierarchical Inheritance
NOTE: You need a public StartUp class with the namespace Farm. Create three classes named Animal, Dog and Cat.
Animal with a single public method Eat() that prints: “eating…”
Dog with a single public method Bark() that prints: “barking…” Cat with a single public method Meow() that prints: “meowing…” Dog and Cat should inherit from Animal.

Part II: Reusing Classes
4. Random List
NOTE: You need a public StartUp class with the namespace CustomRandomList.
Create a RandomList class that has all the functionality of List<string>.
Add additional function that returns and removes a random element from the list.
• Public method: RandomString(): string
5. Stack of Strings
NOTE: You need a public StartUp class with the namespace CustomStack.
Create a class StackOfStrings which extends Stack and can store only strings and has the following functionality:
• Public method: IsEmpty(): bool
• Public method: AddRange(): Stack<string>
