Let's play around with object-oriented programming in Csharp, shall we? Here are five practical examples: ## 1. Modeling a car: ```csharp class Car { public string Brand { get; set; } public string Model { get; set; } public int Year { get; set; } public void Start() { Console.WriteLine("The car is started."); } public void Stop() { Console.WriteLine("The car is stopped."); } } // Usage: Car myCar = new Car(); myCar.Brand = "Toyota"; myCar.Model = "Corolla"; myCar.Year = 2020; myCar.Start(); ``` <br> --- ## <br>2. Bank account management: ```csharp class BankAccount { public string AccountNumber { get; set; } public decimal Balance { get; private set; } public void Deposit(decimal amount) { Balance += amount; } public void Withdraw(decimal amount) { if (amount <= Balance) { Balance -= amount; } else { Console.WriteLine("Insufficient balance."); } } } // Usage: BankAccount myAccount = new BankAccount(); myAccount.AccountNumber = "123456"; myAccount.Deposit(1000); myAccount.Withdraw(500); ``` <br> --- ## <br>3. Representation of employees: ```csharp class Employee { public string Name { get; set; } public string Position { get; set; } public decimal Salary { get; set; } } // Usage: Employee newEmployee = new Employee(); newEmployee.Name = "John"; newEmployee.Position = "Developer"; newEmployee.Salary = 3000; ``` <br> --- ## <br>4. Handling products in a sales system: ```csharp class Product { public string Name { get; set; } public decimal Price { get; set; } public int Stock { get; set; } } // Usage: Product newProduct = new Product(); newProduct.Name = "T-shirt"; newProduct.Price = 20; newProduct.Stock = 100; ``` <br> --- ## <br>5. Implementation of a game with classes for player and enemy: ```csharp class Character { public string Name { get; set; } public int HealthPoints { get; set; } public void Attack(Character target) { Console.WriteLine($"{Name} attacked {target.Name}!"); // Logic to calculate damage, etc. } } // Usage: Character player = new Character(); player.Name = "Hero"; player.HealthPoints = 100; Character enemy = new Character(); enemy.Name = "Villain"; enemy.HealthPoints = 80; player.Attack(enemy); ``` These examples demonstrate how you can use object-oriented programming in C# to model and interact with different types of objects in your programs.
