im tryna add names and ages from all the objects

Tvde1•14mo ago

Can you tell us what the error at the red line says? :)

AhmedOP•14mo ago

into a dictionary

AhmedOP•14mo ago

Tvde1•14mo ago

can you try guess what this error means?

Jimmacle•14mo ago

not gonna lie, this code makes 0 sense

AhmedOP•14mo ago

i don't even know

Tvde1•14mo ago

you start somewhere, Jimmacle 😄

AhmedOP•14mo ago

💀 word

Jimmacle•14mo ago

right but some extra info is needed to figure out what your end goal is, because it's not clear from the code itself

Tvde1•14mo ago

Human.name would try to access a field or property name which is static on Human

Hazel 🌊💃•14mo ago

If you're trying to use a dictionary, why can't you guess at what the error means? 🤔

Tvde1•14mo ago

but name is a non-static instance field

AhmedOP•14mo ago

name isn't static

Hazel 🌊💃•14mo ago

That's their point.

AhmedOP•14mo ago

it's public string

Tvde1•14mo ago

so you have to either use this.name or, take it from an instance of Human

cypherpotato•14mo ago

Add(name, age) just remove "Human" when u specify Human.age you're referencing the static field age

Hazel 🌊💃•14mo ago

Can't do that eithr. Need an instance.

Tvde1•14mo ago

we are in the ctor :)

Hazel 🌊💃•14mo ago

cypherpotato•14mo ago

but hes running that from the constructor

Hazel 🌊💃•14mo ago

I'll see myself into my corner of shame.

cypherpotato•14mo ago

he is in the instance.

AhmedOP•14mo ago

ye so do i make them static

Tvde1•14mo ago

you don't want them static

cypherpotato•14mo ago

nameAndAge should be Dictionary<string, int>

Tvde1•14mo ago

you might want them public

cypherpotato•14mo ago

AhmedOP•14mo ago

they r huh

cypherpotato•14mo ago

where are nameAndAge defined? ah i see now

Tvde1•14mo ago

yeah the next point is that the dictionary expects a Human as a key and a Human as a value. You probably want Name as a key and age as a value

AhmedOP•14mo ago

i did that

cypherpotato•14mo ago

Dictionary<Human, Human> nameAndAge there you should add an keyvalue pair of humans and humans and im pretty sure you dont want it and what u got?

AhmedOP•14mo ago

0 cause of my first line

Console.WriteLine(Human.objectCount);

Console.WriteLine(Human.objectCount);

im meant to get 3 tho huh'

cypherpotato•14mo ago

why not? you called new Human() three times

AhmedOP•14mo ago

idek apparently its cause im overpopulating my constructor

Tvde1•14mo ago

do you understand what the constructor is for?

cypherpotato•14mo ago

whats the purpose of nameAndAge dictionary?

AhmedOP•14mo ago

not really nothing, just testing things

cypherpotato•14mo ago

constructor is an method that is called on the object initialization

Tvde1•14mo ago

the constructor is run whenever a new object Human is created

AhmedOP•14mo ago

yeah ik

cypherpotato•14mo ago

for each new Human(), you call your constructor once on it

AhmedOP•14mo ago

oh wait wait wait

Tvde1•14mo ago

😄

AhmedOP•14mo ago

still didn't work i removed the loop you're right

Console.WriteLine(Human.objectCount);
Console.ReadLine();

Human bob = new Human("Bob", 18);
Human bobby = new Human("Bobby", 16);
Human bibby = new Human("Bibby", 11);

class Human
{
    private string name {get; set;}
    private int age {get; set;}
    public static int objectCount;

    Dictionary<string, int> nameAndAge = new Dictionary<string, int>();

    public Human(string name, int age)
    {

        this.name = name;
        this.age = age;
        objectCount++;

        Console.WriteLine($"{this.name}'s age is {this.age} and he has connected.");

        nameAndAge.Add(name, age);

    }
}

Console.WriteLine(Human.objectCount);
Console.ReadLine();

Human bob = new Human("Bob", 18);
Human bobby = new Human("Bobby", 16);
Human bibby = new Human("Bibby", 11);

class Human
{
    private string name {get; set;}
    private int age {get; set;}
    public static int objectCount;

    Dictionary<string, int> nameAndAge = new Dictionary<string, int>();

    public Human(string name, int age)
    {

        this.name = name;
        this.age = age;
        objectCount++;

        Console.WriteLine($"{this.name}'s age is {this.age} and he has connected.");

        nameAndAge.Add(name, age);

    }
}

but why is it still writing 0

cypherpotato•14mo ago

because you're calling it before you define each human you're calling objectCount++ on constructor, which is called on new Human

cypherpotato•14mo ago

what you mean? are u talking about the dictionary or the first writeline?

Tvde1•14mo ago

you first write the count and then add 3 humans :)

Jimmacle•14mo ago

code in a method runs from the top down, you have to do the stuff you want to run first at the top

cypherpotato•14mo ago

how to run this code snippet?

Hazel 🌊💃•14mo ago

Console.WriteLine(Human.objectCount);

Console.WriteLine(Human.objectCount);

This is still wrong. $eval

MODiX•14mo ago

To compile C# code in Discord, use !eval Example:

!eval for(int i = 0; i < 4; i++) Console.WriteLine(i);

!eval for(int i = 0; i < 4; i++) Console.WriteLine(i);

Please don't try breaking the REPL service. Also, remember to do so in #bot-spam!

Tvde1•14mo ago

is it?

Hazel 🌊💃•14mo ago

Oh chiz, it was made static; okay 😄 I stand corected.

Tvde1•14mo ago

Hazel are you sleepy?

Hazel 🌊💃•14mo ago

Yeah It always was 😭

Tvde1•14mo ago

😄

Hazel 🌊💃•14mo ago

Back to my corner of shame. Byeeeee lol

Jimmacle•14mo ago

maybe we should direct this person to writing the code in a more logical way instead of whatever this is turning into peepoE
