Which part are you struggling with?

BabySid•9mo ago

the starting

mtreit•9mo ago

Show what code you have written so far

BabySid•9mo ago

I haven't started yet

mtreit•9mo ago

I would suggest giving it a try and if you have specific questions on code you can't get working you can ask here. We aren't going to write it for you.

Pobiega•9mo ago

Then you need to start. The task is fairly well described already Start with taking the required inputs and work from there

more donuts -> less money

GaSkia•9mo ago

u solved?

Isaaaak•9mo ago

I solved it (I know it was easy, but I'm a beginner so)

BabySid•9mo ago

I did something I ain't sure if its correct

Isaaaak•9mo ago

Post it

BabySid•9mo ago

using System; class Program { static void Main() { const double costPerDonut1to4 = 2.00; const double costPerDonut5to9 = 1.75; const double costPerDonut10OrMore = 1.50; const double costPerDonut12OrMore = 1.00; const double hstRate = 0.13; const double coverCharge = 0.25; Console.Write("Enter your last name: "); string lastName = Console.ReadLine(); Console.Write("Enter the number of donuts you want to purchase: "); int donutsPurchased = int.Parse(Console.ReadLine()); double totalCost = 0; if (donutsPurchased <= 4) { totalCost = donutsPurchased * costPerDonut1to4; } else if (donutsPurchased < 10) { totalCost = donutsPurchased * costPerDonut5to9; } else { totalCost = donutsPurchased * costPerDonut10OrMore; } // Check if the customer is eligible for HST exemption if (donutsPurchased < 12) { totalCost += totalCost * hstRate; } totalCost += coverCharge; Console.WriteLine($"Total cost: ${totalCost:F2}"); } } what bout this

Isaaaak•9mo ago

Looks pretty good, but there are some errors in how you calculate the total cost. Maybe try calculating it manually (with a calculator) for 15 donuts using the original table and see if it matches up, and if it doesn't, why?

mtreit•9mo ago

@BabySid that looks like a pretty good first attempt but I'm not sure you quite followed this table:

BabySid•9mo ago

 using System;

class Program
{
    static void Main()
    {
        const double costPerDonut1to4 = 2.00;
        const double costPerDonut5to9 = 1.75;

        const double costPerDonut12OrMore = 1.00;
        const double hstRate = 0.13;
        const double coverCharge = 0.25;

Console.Write("Enter your last name: ");
string lastName = Console.ReadLine();

        Console.Write("Enter the number of donuts you want to purchase: ");
        int donutsPurchased = int.Parse(Console.ReadLine());

        double totalCost = 0;

        if (donutsPurchased <= 4)
        {
            totalCost = donutsPurchased * costPerDonut1to4;
        }
        else if (donutsPurchased < 10)
        {
            totalCost = donutsPurchased * costPerDonut5to9;
        }
        else

        // Check if the customer is eligible for HST exemption
        if (donutsPurchased < 12)
        {
            totalCost += totalCost * hstRate;
        }

        totalCost += coverCharge;

        Console.WriteLine($"Total cost: ${totalCost:F2}");
    }
}

        {
            totalCost = donutsPurchased * costPerDonut1to4;
        }
        else if (donutsPurchased < 10)
        {
            totalCost = donutsPurchased * costPerDonut5to9;
        }
        else
        {
            totalCost = donutsPurchased * costPerDonut10OrMore;

    }
}

Isaaaak•9mo ago

hah I was first :P

mtreit•9mo ago

🥷

BabySid•9mo ago

I didn't understand it properly could you explain it once more please?

Isaaaak•9mo ago

Oooh wait maybe I've misunderstood this slightly Is this pricing $ for the total donuts or does the pricing only apply to the donuts above that level? Like say I buy 15 donuts, does that mean it's 15*$1 = $15 or is it more than that because the earlier donuts are more expensive?

mtreit•9mo ago

It should be the former Based on how I read the assignment

BabySid•9mo ago

yes its $15 plus cover charge

Isaaaak•9mo ago

I thought so too, at first. But maybe not? idk

mtreit•9mo ago

BabySid•9mo ago

oh shi- hold on I see it

SinFluxx•9mo ago

A single donut is also its own price, not 1-4 as a bracket

BabySid•9mo ago

so 1 donut is 2 dollars 2donuts to 4 donuts is 1.75 dollars 5 donuts to 9 donuts is 1.50 dollars 10 donuts onwards its 1 dollar right?

Isaaaak•9mo ago

yeah but

BabySid•9mo ago

shi-

Isaaaak•9mo ago

I'm still not sure if it's like each donut has it's own price or if all the donuts cost $1 if i buy 10 donuts Like either all cost $1 each = $10 or 1st donut cost $2, second to fourth donut $1.75 etc. leading to a higher sum

SinFluxx•9mo ago

I'd assume the simpler pricing from the wording, it's not income tax!

Isaaaak•9mo ago

it's a bit ambigous

mtreit•9mo ago

The table is pretty clear

Isaaaak•9mo ago

but the problem is then it's much more expensive to buy 9 donuts than 10 lol buy 12 donuts for the same price as 9? xD doesn't make much sense from a business perspective anyways, too much logic for a simple problem

SinFluxx•9mo ago

🤷 I don't think it's meant to represent a legitimate business

BabySid•9mo ago

uhgg I need to fix this now lol

mtreit•9mo ago

I would use pattern matching I think to have a nice clean way of expressing the cost-per-donut calculation but for a beginner problem that's probably not a good idea.

BabySid•9mo ago

ummmm

Isaaaak•9mo ago

const double costPerDonut1to4 = 2.00; // Is this correct? I think in the table it says if you buy 1 donut it is $2, but if you buy 2 to 4 donuts it's $1.75 per donut
const double costPerDonut5to9 = 1.75; // I think the table says 5 to 9 donuts is $1.50
const double costPerDonut10OrMore = 1.50; // Same here, should be $1.00
const double costPerDonut12OrMore = 1.00; // Unnecessary, isn't used
const double hstRate = 0.13;
const double coverCharge = 0.25;

Console.Write("Enter your last name: ");
string lastName = Console.ReadLine();

Console.Write("Enter the number of donuts you want to purchase: ");
int donutsPurchased = int.Parse(Console.ReadLine());

double totalCost = 0; // you could add the cover charge here already

if (donutsPurchased <= 4)

    totalCost = donutsPurchased * costPerDonut1to4;

    totalCost += totalCost * hstRate;
}

totalCost += coverCharge;

Console.WriteLine($"Total cost: ${totalCost:F2}");

// you need to add a check to see if donutsPurchased is atleast 1, if it isn't the program should exit immediatly (because you can't order less than 1 donut)

const double costPerDonut1to4 = 2.00; // Is this correct? I think in the table it says if you buy 1 donut it is $2, but if you buy 2 to 4 donuts it's $1.75 per donut

added some comments

SinFluxx•9mo ago

Why does the hstRate calculation need changing?

Isaaaak•9mo ago

oh shit nvm it doesn't wow I'm stupid it's just another way of doing it

SinFluxx•9mo ago

The only other thing is just to check you're outputting all the required information at the end blobthumbsup

BabySid•9mo ago

wow okay lemem give this a whirl

Isaaaak•9mo ago

Also maybe consider which data type should be used when money is involved

SinFluxx•9mo ago

And as @Isaaaak pointed out that you can add the cover charge earlier, especially as the instructions say the cover charge is pre hst

BabySid•9mo ago

oh okay so I check for hst after adding the covercharge?

Isaaaak•9mo ago

yep

SinFluxx•9mo ago

Yeah 🙂

BabySid•9mo ago

hmmm okay thank you so much

Isaaaak•9mo ago

because the cover charge is also taxed

BabySid•9mo ago

I'll brb oh

cs how about now its working the subtotal is correct

Isaaaak•9mo ago

1. What happens if a customer orders 1 donut? In the table it says 1 donut should cost $2 2. What happens if the customers says they want 0 or a negative amount of donuts? What should happen? (what does the original question say?) 3. Which datatype should be used when we are talking about money in C#? Is double correct or is there a better one? 4. Are you outputting everything the original question says you should output? 5. Is the last "else"-statement necessary?

cs I fixed for the 0 or negative one first one as well

BabySid•9mo ago

Also how would I output this ?

Isaaaak•9mo ago

Same as you outputted cost, just copy that two more times and change the text + variable (in the right order ofc) very nice, works good

BabySid•9mo ago

wait I didn't comprehend this

Isaaaak•9mo ago

Console.WriteLine($"Total cost: ${totalCost:F2}"); Copy this, but change it slightly so you get the right text and the right variable

mtreit•9mo ago

There is a crashing bug in that code.

BabySid•9mo ago

aha gotcha wait wha?

Isaaaak•9mo ago

You have two "if"-statements here. What problems could arise? Do you get the correct total cost if you order 1 donut?

mtreit•9mo ago

See what happens when the user types "three" instead of "3"

Isaaaak•9mo ago

I don't think there are any requirements that the user should be able to input anything else other than integers?

mtreit•9mo ago

Users never follow the rules 😉 Although I think the instructions did say you can assume it will be a valid integer. But in other contexts you would want to think about this kind of thing.

Isaaaak•9mo ago

Yep, error-handling is important

step through that mentally and see what happens...

cs apologies

1. What happens if a customer orders 1 donut? In the table it says 1 donut should cost $2. What should the total sum be when a customer buys 1 donut (calculate manually and compare to what your program says)? If they don't add up, why? wait nvm you fixed this one^^ 2. Which data type should be used when we are talking about money in C#? Is double correct or is there a better one? 3. Is the last "else"-statement necessary?

BabySid•9mo ago

the first one I've calculated I guess for the second one we've been taught double only third one 😁

Isaaaak•9mo ago

ooh wait I've found something If we calculate 1 donut manually we get (2+0.25)*1.13 = $2,54 but the program says $2.51 How come?

BabySid•9mo ago

I'll check just a sec

Isaaaak•9mo ago

I'll give you a hint if you don't figure it out

BabySid•9mo ago

I discovered something else as well I still can't see this can you figure out why 😢

Isaaaak•9mo ago

I think it looks good?

BabySid•9mo ago

hold on but when I input 0 or any negative number it doesn't show the following for rest of em it shows the following

Isaaaak•9mo ago

For me it does

Isaaaak•9mo ago

Maybe you have it so your console instantly closes when the program ends? If so, you can just add an empty Console.ReadLine(); under the error statement

Isaaaak•9mo ago

mtreit•9mo ago

You should put something like:

Console.WriteLine("Press <Enter> to exit the program.");

Console.WriteLine("Press <Enter> to exit the program.");

so the user isn't left staring at the screen wondering why the program doesn't finish.

BabySid•9mo ago

oh yeh I fixed it thank you so much

Isaaaak•9mo ago

still wrong total cost though hmmhm

BabySid•9mo ago

nono
