C sharp - class and object in C#

What is a Class in C#?

A class in C# is a blueprint or template for creating objects. It defines properties (data) and methods (behavior).Think of a class like a blueprint for a car. The class defines what a car has (wheels, color) and does (drive, brake).

What is an Object in C#?

An object is an instance of a class. It holds real data and can use the class's methods and properties.Using the blueprint (class), you can create many real cars (objects).

        Console.WriteLine(brand + " is starting.");
    }
}

class Program
{
    static void Main()
    {
     Car myCar = new Car();
      myCar.brand = "Toyota";
        myCar.year = 2022;
        Console.WriteLine("Brand: " + myCar.brand);
        Console.WriteLine("Year: " + myCar.year);
