What is an object?

What is an Object in OOP?

In object-oriented programming (OOP), an object is an instance of a class. A class is a blueprint, and an object is the actual usable form created from that blueprint. Objects contain data (attributes) and behaviors (methods).

Example in C#

Here is a simple class and object example:

class Car
{
    public string Color;
    public int Speed;

    public void Accelerate()
    {
        Speed += 10;
    }
}

Car myCar = new Car();
myCar.Color = "Red";
myCar.Speed = 60;

myCar.Accelerate();
Console.WriteLine(myCar.Speed);  // Output: 70

    

Objects in Memory

In C#, objects are stored in the heap, while the reference variable (like myCar) is stored on the stack. Each object has its own data and can call its own methods.
