Classes and objects

Context: Classes are blueprints for creating objects. Objects are instances of classes. This section introduces the fundamental concepts of OOP in C#.

A class defines a data structure and the operations that can be performed on that data. An object is a concrete instance of a class, allocated in memory.

// Class definition
class Car
{
    public string Model;
    public void Drive() => Console.WriteLine("Driving");
}

// Creating objects
Car myCar = new Car();
myCar.Model = "Tesla";
myCar.Drive();
