im tryna add names and ages from all the objects

Tvde1•2y ago

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

احمدOP•2y ago

into a dictionary

احمدOP•2y ago

Tvde1•2y ago

can you try guess what this error means?

Jimmacle•2y ago

not gonna lie, this code makes 0 sense

احمدOP•2y ago

i don't even know

Tvde1•2y ago

you start somewhere, Jimmacle 😄

احمدOP•2y ago

💀 word

Jimmacle•2y 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•2y ago

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

Hazel 🌊💃•2y ago

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

Tvde1•2y ago

but name is a non-static instance field

احمدOP•2y ago

name isn't static

Hazel 🌊💃•2y ago

That's their point.

احمدOP•2y ago

it's public string

Tvde1•2y ago

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

cypherpotato•2y ago

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

Hazel 🌊💃•2y ago

Can't do that eithr. Need an instance.

Tvde1•2y ago

we are in the ctor :)

Hazel 🌊💃•2y ago

cypherpotato•2y ago

but hes running that from the constructor

Hazel 🌊💃•2y ago

I'll see myself into my corner of shame.

cypherpotato•2y ago

he is in the instance.

احمدOP•2y ago

ye so do i make them static

Tvde1•2y ago

you don't want them static

cypherpotato•2y ago

nameAndAge should be Dictionary<string, int>

Tvde1•2y ago

you might want them public

cypherpotato•2y ago

احمدOP•2y ago

they r huh

cypherpotato•2y ago

where are nameAndAge defined? ah i see now

Tvde1•2y 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

احمدOP•2y ago

i did that

cypherpotato•2y 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?

احمدOP•2y ago

0 cause of my first line

Console.WriteLine(Human.objectCount);

Console.WriteLine(Human.objectCount);

im meant to get 3 tho huh'

cypherpotato•2y ago

why not? you called new Human() three times

احمدOP•2y ago

idek apparently its cause im overpopulating my constructor

Tvde1•2y ago

do you understand what the constructor is for?

cypherpotato•2y ago

whats the purpose of nameAndAge dictionary?

احمدOP•2y ago

not really nothing, just testing things

cypherpotato•2y ago

constructor is an method that is called on the object initialization

Tvde1•2y ago

the constructor is run whenever a new object Human is created

احمدOP•2y ago

yeah ik

cypherpotato•2y ago

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

احمدOP•2y ago

oh wait wait wait

Tvde1•2y ago

😄

احمدOP•2y 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•2y ago

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

cypherpotato•2y ago

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

Tvde1•2y ago

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

Jimmacle•2y 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•2y ago

how to run this code snippet?

Hazel 🌊💃•2y ago

Console.WriteLine(Human.objectCount);

Console.WriteLine(Human.objectCount);

This is still wrong. $eval

MODiX•2y 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•2y ago

is it?

Hazel 🌊💃•2y ago

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

Tvde1•2y ago

Hazel are you sleepy?

Hazel 🌊💃•2y ago

Yeah It always was 😭

Tvde1•2y ago

😄

Hazel 🌊💃•2y ago

Back to my corner of shame. Byeeeee lol

Jimmacle•2y ago

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