Do just that Instead of setting your value to 10, set it to the current value plus 10

Ezlanding•3y ago

So like n +=10?

SquirtleOP•3y ago

example int balance int deposit deposit // sets by the user typing it and then balance += deposit so something like that

Angius•3y ago

Yes

SquirtleOP•3y ago

but then when i type in a new deposit the balance sets to the current deposit i typed my deposit beforehand doesnt exist

Show $code

if you know what i mean

Ezlanding•3y ago

Are you restarting the program every time?

no it is in another language but hope you get it

Your instatdgausding method is said to be returning something But you don't do anything with that return

SquirtleOP•3y ago

tbh i dont know what return really does haha

Angius•3y ago

It returns the value from the inside of the method, to the outside of it

SquirtleOP•3y ago

ah should i remove the return value and add a void instead?

Assuming saldo is the one you want Keep the saldo Int at the top because you make a new one every time the function is called $scope

MODiX•3y ago

you probably want $scopes

Ezlanding•3y ago

$scopes

MODiX•3y ago

scope A {
  thing a;
  scope B {
    thing b;
  }
}

scope A {
  thing a;
  scope B {
    thing b;
  }
}

thing a is available in scope A and scope B thing b is available only in scope B

Angius•3y ago

You should be using this value This method returns your sedlar But since you don't assign the return to anything when the method is called, it's discarded Then your saldo method has an inner variable saldo that exists only within that method

SquirtleOP•3y ago

will this work for me ?

Angius•3y ago

Do you need to sum two numbers? Then no It's just an example demonstrating what return does

SquirtleOP•3y ago

Ezlanding•3y ago

Is saldo or sedlar the “balance”

SquirtleOP•3y ago

saldo is the blaance balance* insättning is withdraw sedlar is money

Angius•3y ago

(would've been a whole lot easier if your code was in English 😛 )

SquirtleOP•3y ago

hahahahahahahaha can rewrite it fast in english

Ezlanding•3y ago

I think you should keep saldo at the top because the saldo method creates a new saldo every time it’s called

Angius•3y ago

Yeah

public class Program
{
    private static int _balance;

    public static void Main()
    {

    }

    private static int TakeDeposit()
    {

    }

    public static void DisplayBalance()
    {
  
    }
}

public class Program
{
    private static int _balance;

    public static void Main()
    {

    }

    private static int TakeDeposit()
    {

    }

    public static void DisplayBalance()
    {
  
    }
}

That should be just about the structure

@Squirtle try this at the top. Does it work?

namespace switch_övning_5_bankkomat
{
    internal class Program
    {
        static int money;
        static int balance;
        static void Main(string[] args)
        {
            bool sant = true;

…

namespace switch_övning_5_bankkomat
{
    internal class Program
    {
        static int money;
        static int balance;
        static void Main(string[] args)
        {
            bool sant = true;

…

Note that the only change I made was adding a balance at the top (Also make sure to change the

int balance += money

int balance += money

balance += money

balance += money

SquirtleOP•3y ago

yeah did it doesnt work S; still same issue when it gets the money amount but then when i try to put in a new value it doesnt change it changes to the new only it doesnt add the old one

Angius•3y ago

The balance needs to be in the scope of the class Then, the withdraw/deposit method needs to modify that balance Then, the display method has to display that balance

Ezlanding•3y ago

@Squirtle found the problem. Your code says =+ when it should be +=

SquirtleOP•3y ago

lmao that fixed it hahahahahahhahahaah

Ezlanding•3y ago

(On a side note it’s interesting how c# has a + unary operator when I can’t think of a use for it)
