Challenge: Constructors

メニュヌを衚瀺するにはスワむプしおください

A simple class called Dog is given. Create a constructor which takes in the arguments name, breed, age, and initializes the fields from the values of arguments.

index.cs

index.cs


              
123456789101112131415161718192021222324

            
using System;

class Dog {
    public string name;
    public string breed;
    public int age;
    
    // Write constructor code below this line
    
    // Write constructor code above this line
    
    public void bark() {
        Console.WriteLine("Woof!");
    }
}

public class ConsoleApp
{
    public static void Main(string[] args)
    {
        Dog dog = new Dog("Dobby", "Dobermann", 4);
        dog.bark();
    }
}

In order to assign the argument values to the fields without raising any error you'll have to use this operator, since the arguments are the same name as the fields.

using System;

class Dog {
    public string name;
    public string breed;
    public int age;
    
    // Write constructor code below this line
    public Dog(string name, string breed, int age) {
        this.name = name;
        this.breed = breed;
        this.age = age;
    }
    // Write constructor code above this line
    
    public void bark() {
        Console.WriteLine("Woof!");
    }
}

public class ConsoleApp
{
    public static void Main(string[] args)
    {
        Dog dog = new Dog("Dobby", "Dobermann", 4);
        dog.bark();
    }
}
