Programming a menu on WinForms

Coding a Pizza menu selector that outputs the price, thinking i could mainly use if and else if statements along with “/n”, a bit stuck on how to make the values add together tho. Should I assign them as double datatypes? I got my code to work to just show them after pressing button, a bit stuck on the math I need to sum these and output a subtotal, make a tax variable and have a total. Anyone think they can help?

I actually was able to get the strings to show, just dont know how to do calculations

double

double

could be fine for learning, but

decimal

decimal

would be better for handling this kind of values
what's the problem with calculations, percentages? getting the values?

Ddance?`double` could be fine for learning, but `decimal` would be better for handling ...

Hi, I am having issues getting the values, will send pic of code

dance?•11/11/23, 3:28 PM

pasting code as text would be better...

Ddance?pasting code as text would be better...

Will do too!

ArrayOP•11/11/23, 3:31 PM

Sorry

ArrayOP•11/11/23, 3:32 PM

I appreciate you for helping me I have been stuck for so long

ArrayOP•11/11/23, 3:32 PM

I am new to C# so I appreciate the help

@dont

ArrayOP•11/11/23, 3:45 PM

I am not sure how to assign these items number values and add them. Was thinking I could assign them a double value and add them after but I'm not sure how to go about it

dance?•11/11/23, 3:56 PM

ah ok so you have the strings, but you don't really have a place where you are keeping the relation between the price and the item

Ddance?ah ok so you have the strings, but you don't really have a place where you are k...

ArrayOP•11/11/23, 3:57 PM

Right!

ArrayOP•11/11/23, 3:58 PM

I was thinking of making up a variable called double and seeing if I could assign it to everything with their price

dance?•11/11/23, 3:58 PM

which is ironic for a guy called Array

ArrayOP•11/11/23, 3:58 PM

LOOOOL

ArrayOP•11/11/23, 3:58 PM

I can tell you a funny story

ArrayOP•11/11/23, 3:58 PM

About my name

ArrayOP•11/11/23, 3:58 PM

I actually just got into Comp Sci

ArrayOP•11/11/23, 3:58 PM

I called myself Array since I was like 10

ArrayOP•11/11/23, 3:59 PM

I had no idea I would want to study it though

ArrayOP•11/11/23, 3:59 PM

I’ve always loved math though

ArrayOP•11/11/23, 3:59 PM

Been my best subject

ArrayOP•11/11/23, 3:59 PM

But my career path was wanted to do med stuff

ArrayOP•11/11/23, 3:59 PM

But I think I just decided to do something I think I’m actually good at and have interest in

ArrayOP•11/11/23, 3:59 PM

Had Discord since 2016 so maybe it was meant to be

ArrayOP•11/11/23, 3:59 PM

Ddance?which is ironic for a guy called Array

ArrayOP•11/11/23, 4:00 PM

I actually haven’t learned about Array’s yet

ArrayOP•11/11/23, 4:00 PM

In computer science

dance?•11/11/23, 4:00 PM

in this way you should get the price from the text
which would be way more complicated than learn about arrays
i mean, it's not that much difficult, it's like one line of code, but still you would need arrays

Ddance?in this way you should get the price from the text which would be way more compl...

ArrayOP•11/11/23, 4:01 PM

Hmm, maybe I could make the variable double at the top instead of string?

ArrayOP•11/11/23, 4:02 PM

Or is there a way to parse it into a double

dance?•11/11/23, 4:02 PM

not really, that's a string

ArrayOP•11/11/23, 4:02 PM

Gotcha

dance?•11/11/23, 4:02 PM

to me the smartest move right now would be having the price in a ~~switch~~ series of ifs and checking for checked for every group of items

ArrayOP•11/11/23, 4:04 PM

Makes sense, so like two diff button?

ArrayOP•11/11/23, 4:04 PM

Or how would you go about coding that

ArrayOP•11/11/23, 4:05 PM

It’s just odd because I know how to do console integer calculations … like I could name it Side A and give it a number value as a double datatype. Just confused why it doesn’t work here

ArrayOP•11/11/23, 4:05 PM

Like hypothetically why can’t I add to each if statement a double variable and name it price and assign it a number value

ArrayOP•11/11/23, 4:06 PM

Or something for each category

dance?•11/11/23, 4:07 PM

not two buttons but two variables
you already have the various if for building the final text
you can just re-use those to add the price too
without parsing it, but hey, baby steps

ArrayOP•11/11/23, 4:07 PM

Thanks for patient, I appreciate you being kind bc I am really new to this

ArrayOP•11/11/23, 4:08 PM

Ok, let me try to understand this rq

ArrayOP•11/11/23, 4:08 PM

Also here is what I am supposed to be doing, (I could have messed up with the way I communicated my problem)
