❔ what's an object?

SSoinagie2/25/2023

Can somebody please explain to me in very simple words what's an obkect as I don't understand it from explanations on the internet

AAngius2/25/2023

It's a thing

AAngius2/25/2023

A car is an object

AAngius2/25/2023

A desk is an object

AAngius2/25/2023

The chair you're sitting on is an object

AAngius2/25/2023

It's not any different when it comes to programming

SSoinagie2/25/2023

So it's just a variable?

AAngius2/25/2023

SSoinagie2/25/2023

Like x=10?

AAngius2/25/2023

A variable is the object's address, you could say

SSoinagie2/25/2023

What address

AAngius2/25/2023

How you refer to that specific object

AAngius2/25/2023

Like, you have a Car. But which car do you mean?

SSoinagie2/25/2023

I still don't know what objects are

AAngius2/25/2023

var myCar = new Car();
var yourCar = new Car();

SSoinagie2/25/2023

So Im not sure I understand

AAngius2/25/2023

Two different objects, two different cars

AAngius2/25/2023

So each has a different name

AAngius2/25/2023

There's my car, and there's your car

SSoinagie2/25/2023

And they're both new cars?

AAngius2/25/2023

They're both cars

SSoinagie2/25/2023

New cars

AAngius2/25/2023

new is how you instantiate an object in C#

SSoinagie2/25/2023

What

AAngius2/25/2023

How you create a new instance of a car

AAngius2/25/2023

A new instance of an object

SSoinagie2/25/2023

Idk even know what instantiate means😭

AAngius2/25/2023

To create an instance of

AAngius2/25/2023

An individual thing

AAngius2/25/2023

A class, in C#, is sort of a blueprint for a thing. A concept of it, an idea of it

AAngius2/25/2023

Then, from that class, you can create a specific instance

SSoinagie2/25/2023

Why make new instance of a car?

AAngius2/25/2023

A specific, existing, physical object

AAngius2/25/2023

Because you want an actual car

AAngius2/25/2023

Not just an idea of a car

SSoinagie2/25/2023

You already have it just copy it

AAngius2/25/2023

What if both have different colors?

SSoinagie2/25/2023

But you didn't write that anywhere

AAngius2/25/2023

var myCar = new Car("Ford", "Blue");
var yourCar = new Car("Mazda", "Green");

SSoinagie2/25/2023

Im confused

AAngius2/25/2023

And even in the case of

var myCar = new Car();
var yourCar = new Car();

what if I want to start just a specific car?

AAngius2/25/2023

myCar.Start();

AAngius2/25/2023

I don't want to start the idea of a car

AAngius2/25/2023

I want to start specifically my own car

SSoinagie2/25/2023

What idea?

PPobiega2/25/2023

Are two black fords the same car? no, they are two different instances of a black ford

AAngius2/25/2023

The idea of a thing, the concept of it, not the specific given thing

SSoinagie2/25/2023

What?

AAngius2/25/2023

"A chair" is a general term, a name for the concept of this piece of furniture

AAngius2/25/2023

"A chair" doesn't have colour or shape

AAngius2/25/2023

"The chair" does

AAngius2/25/2023

When I say "chair" it doesn't have colour

AAngius2/25/2023

When I say "my chair" or "your chair" or "that chair over there", they do

AAngius2/25/2023

They're no longer abstract concepts, they're concrete, existing, physical objects

SSoinagie2/25/2023

But only if you put that color in parentheses

AAngius2/25/2023

That's a constructor

AAngius2/25/2023

You can just... not have a constructor, and it can still work

SSoinagie2/25/2023

Sorry I have no idea about the wording and in general Im just lost

AAngius2/25/2023

var myCar = new Car();
var yourCar = new Car();

myCar.Color = "Red";
yourCar.Color = "White";

AAngius2/25/2023

Here, I just set the colour of those cars after creating them

SSoinagie2/25/2023

You just called myCar a variable

SSoinagie2/25/2023

Then isnt it a variable?

AAngius2/25/2023

The variable gives that object a name

SSoinagie2/25/2023

So objects are variables

AAngius2/25/2023

var Soinahie = new Person();

AAngius2/25/2023

Are you your name?

AAngius2/25/2023

Or are you a person, that has a name we can all use to refer to you?

AAngius2/25/2023

var Pobiega = new Person();

AAngius2/25/2023

Two different people, with two different names

SSoinagie2/25/2023

What pobiega?

AAngius2/25/2023

@Pobiega

AAngius2/25/2023

Another user

PPobiega2/25/2023

👋

SSoinagie2/25/2023

I dont understand

AAngius2/25/2023

You don't understand a difference between a person and their name?

AAngius2/25/2023

We use names if we want to refer to specific people

SSoinagie2/25/2023

But what about my name?

PPobiega2/25/2023

What about it?

AAngius2/25/2023

It's how others can tell you apart from other people?

AAngius2/25/2023

It's how others can refer to you?

SSoinagie2/25/2023

So its indetificator for an object?

AAngius2/25/2023

Yep

PPobiega2/25/2023

in programming we say that "a variable points to an object"

SSoinagie2/25/2023

And its a variable

PPobiega2/25/2023

its two different things. One points to the other

SSoinagie2/25/2023

They just used var

PPobiega2/25/2023

a name points to a person

PPobiega2/25/2023

var variableName = new Person();

PPobiega2/25/2023

var variableName is indeed a variable

PPobiega2/25/2023

but new Person() is not

SSoinagie2/25/2023

Yeah so my identuficator is a variable

PPobiega2/25/2023

yes

SSoinagie2/25/2023

So my name is var

PPobiega2/25/2023

no, var is a keyword

PPobiega2/25/2023

variableName is the name

SSoinagie2/25/2023

I meant short for a varaible

PPobiega2/25/2023

okay, then yes

SSoinagie2/25/2023

My name is a variable string
