not sure if you're trolling or legitimate asking a question with your code indented like that sorry can you resubmit the file so its readable at least? CTRL+K+D if you're using visual studio to format your code

Jimmacle•2d ago

yeah that formatting is wild

MohaOP•2d ago

I'm on mobile, I just started coding yesterday..

leowest•2d ago

fair then if u would format the file and reupload that would be helpful for us to help you

MohaOP•2d ago

Yeah sure one sec

mg•2d ago

yeah it looks like you've already written a couple while loops. could you clarify what you're asking?

MohaOP•2d ago

I basically want to start the questions again In the top top And the same proccess

mg•2d ago

In that case, you'd want all the logic of asking the questions and getting answers to be in the body of a while loop

leowest•2d ago

much better yes! thanks

MohaOP•2d ago

Yea but how And I want the loop to be looped Until the user says enough

mg•2d ago

Let's start with that. How are you determining when the user says enough?

taner.•2d ago

put the logic in a while loop

MohaOP•this hour

I'd put a console.readline string in a

if

if

and just

break

break

, isn't that how it works? Oops

taner.•this hour

you already ask the user for yes or no. like while(choice == "yes"){....}

MohaOP•this hour

Why's it like that

mg•this hour

well right now you're using the choice variable, right? you read a string into that variable and check if it's one of a few possible responses

MohaOP•this hour

Yeah I put the while there but I don't know what to loop here Where to start and end

mg•this hour

in this case, you always want to ask the questions at least once, so you're actually going to want a do while loop instead of a while loop

MohaOP•this hour

A while loop doesn't work? I only understand while loops

mg•this hour

a do/while is very similar it just always runs at least once e.g.

while (false) { Console.WriteLine("foo"); } // does nothing
do { Console.WriteLine("foo"); } while (false) // writes "foo" to the console once

while (false) { Console.WriteLine("foo"); } // does nothing
do { Console.WriteLine("foo"); } while (false) // writes "foo" to the console once

MohaOP•this hour

What if I want more than once, also what does while false represent, what if I put true

mg•this hour

what's inside the parentheses is the condition for the while loop: what determines if it'll run again i just used false as an example both will run as long as the condition is true it's just that while checks the condition before running the first time, and do/while doesn't so with do/while, the code inside always runs at least once whereas with while, it may not run at all

MohaOP•this hour

So if I put true it will run forever

mg•this hour

yep

MohaOP•this hour

Ok now that I uh Where do I start the loop what marks the end The while ()?

mg•this hour

        while (choice != "yes" && choice != "yes." && choice != "no" && choice != "no.")
        {
            Console.WriteLine("Please say yes or no!");
            choice = Console.ReadLine().ToLower();
        }

        while (choice != "yes" && choice != "yes." && choice != "no" && choice != "no.")
        {
            Console.WriteLine("Please say yes or no!");
            choice = Console.ReadLine().ToLower();
        }

this one?

MohaOP•this hour

No I want to loop the whole code over and over again until a break happens The "do" marks the beginning of the loop and "while()" marks the end?

mg•this hour

correct but you'll need some code before do specifically you'll need to declare the variable that holds the user's answer

MohaOP•this hour

String choice; ?

mg•this hour

yep, but use lowercase string

MohaOP•this hour

And where do I put the value

mg•this hour

not a functional difference, it's just conventional C# before the loop, should choice even have a value?

MohaOP•this hour

choice is a readline

mg•this hour

it's a variable you're assigning the output of Console.ReadLine().ToLower() to it

MohaOP•this hour

Yes

mg•this hour

but it's just a variable. it can remain uninitialized so before the loop, should it have a value?

MohaOP•this hour

mg•this hour

right

MohaOP•this hour

When I declare the thing assigned It should be at that time when I ask if the user wants to continue doing actions Am I correct

mg•this hour

yep

MohaOP•this hour

So I would uhh Put it in line 74 whatever

mg•this hour

so your code will look like

string choice;
do
{
  // ask about withdrawing, depositing, etc.
  // do the withdrawal, deposit, etc.
  // ask if the user wants to go again, so now choice has a value
}
while (/* what goes here? */);

string choice;
do
{
  // ask about withdrawing, depositing, etc.
  // do the withdrawal, deposit, etc.
  // ask if the user wants to go again, so now choice has a value
}
while (/* what goes here? */);

MohaOP•this hour

Goes true Also uhh

mg•this hour

do you want it to keep going forever?

MohaOP•this hour

What if I want the loop to be in a if Until the user commands it to stop Line 73

mg•this hour

so we definitely don't want true in the parentheses, otherwise it'll just keep going forever

MohaOP•this hour

But false makes it go only once right?

mg•this hour

there are infinitely many options other than true and false

MohaOP•this hour

Or do u mean once every run

mg•this hour

you've got the logic there already, if (choice == "yes" || choice == "yes.")

MohaOP•this hour

Or once every time the user wants to keep going

mg•this hour

so choice == "yes" || choice == "yes." is what goes in the parentheses of the do/while

MohaOP•this hour

Ok I'm dumb

mg•this hour

that's a regular feeling in this line of work

MohaOP•this hour

Ok now time to do it How did the do command work Do{} ? @mg

mg•this hour

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/statements/iteration-statements#the-do-statement

Iteration statements -for, foreach, do, and while - C# reference

C# iteration statements (for, foreach, do, and while) repeatedly execute a block of code. You use those statements to create loops or iterate through a collection.

MohaOP•this hour

Oh I put the while outside the do Why is it giving me this error?

MohaOP•this hour

leowest•this hour

if u read the error it tells u what is missing there

leowest•this hour

MohaOP•this hour

I filled the errors and it gave me more errors 🥲

leowest•this hour

im not sure what filled means can u provide code? if you look at the link above, a do while is written like this

do
{
    // body
} while (condition);

do
{
    // body
} while (condition);

you need to close it with the semicolon

MohaOP•this hour

I filled a } before a ; So it became like ;} On another error I messed up something

leowest•this hour

can you show the code?

MohaOP•this hour

I CANT FIND IT

glhays•this hour

In most cases this will be an error ;}

leowest•this hour

            while (choice != "yes" && choice != "yes." && choice != "no" && choice != "no.") ;
 
        }  {
            Console.WriteLine("Please say yes or no!");
            choice = Console.ReadLine().ToLower();
        }

            while (choice != "yes" && choice != "yes." && choice != "no" && choice != "no.") ;
 
        }  {
            Console.WriteLine("Please say yes or no!");
            choice = Console.ReadLine().ToLower();
        }

I guess the problem is around here? by adding a ; after the () in the while u essentially terminated the while then u have broken brackets }{} its important that every time u open a bracket u know there is a pairing bracket for it AKA

{
}

{
}

MohaOP•this hour

Yeah It looks so wrong

leowest•this hour

yes, its what u have in your code.

MohaOP•this hour

On second

mg•this hour

I would forget about the "Please say yes or no" part for now

MohaOP•this hour

What the hell is that bracket doing

leowest•this hour

you probably accidently added it once u broke the while

mg•this hour

just focus on getting the do/while working and you can re-add that part later

leowest•this hour

so you need to fix it by removing the ; and fixing the brackets

Angius•this hour

MohaOP•this hour

I FIXED IT YES the brackets were not positioned well

leowest•this hour

understanding your own code is 10 steps fowards 🙂 if you're using visual studio you can also hover your mouse over the bracket and it shows u what is its other side of the bracket

MohaOP•this hour

Yep

leowest•this hour

so u know they are opening and ending at the right place

MohaOP•this hour

Im using c# shell Mobile app Ok now something went wrong No errors though dawg the app stop wroking

leowest•this hour

Angius•this hour

Writing code on mobile has to be an... experience

MohaOP•this hour

I don't have a pc vruh

glhays•this hour

Remove the space a before the semi-colon while (choice != "yes" && choice != "yes." && choice != "no" && choice != "no.") ;

MohaOP•this hour

Alright

Angius•this hour

I can recommend getting a cheap Bluetooth keyboard if your phone supports it. That's how I did my statistics exam in R in college, since I didn't have a laptop :KEKW:

MohaOP•this hour

I actually used while commands before without semicolons and they worked well.. LOL

mg•this hour

while loops don't need a semicolon at the end, but do/whiles do

MohaOP•this hour

Ok my dumb ahh went straight to put semicolons after whiles

Angius•this hour

Generally, every control flow statement (if, for, foreach, while, switch, (arguably using as well)) is structured like so:

keyword (stuff)
{
    code
}

keyword (stuff)
{
    code
}

One exception being do..while

do {
    code
} while (stuff);

do {
    code
} while (stuff);

MohaOP•this hour

RAHHHHHHHHHHHTR It's the hardest code I did so far Thanks to all who helped Appreciated fr They say don't celebrate too early chat Now -600+1000 is 400 but

MohaOP•this hour

yes

mg•this hour

-600 + 1000 is indeed 400, so your program must not be computing -600 + 1000. it must be computing something else not sure if whatever mobile IDE you're using supports breakpoints but at worst you can Console.WriteLine() to see what the value of different things are at different points in your code's execution
