❔ Making a Vending Machine for Class!

Hey ya'll, I'm new here! I've been having some trouble with this assignment and I was hoping I could get some help. Below is a snippet of my code so far. Below is a snippet of my code so far. Basically, I got the vending loop portion down, but I can't seem to figure out how to get the program to maintain the number of each item and then provide the total when the user ends the program. { Console.WriteLine(" OSU Snacks menu"); Console.WriteLine("Select 1 for Soda --> price = $" + vendingOne); Console.WriteLine("Select 2 for Cookie --> price = $" + vendingTwo); Console.WriteLine("Select 3 for Chips --> price = $" + vendingThree); Console.WriteLine(); string userInput = Console.ReadLine(); double numberSelect = Convert.ToDouble(userInput); if (numberSelect == 1) { Console.WriteLine("You chose soda. How many do you want?"); string quantitySelect = Console.ReadLine(); double qsoda = Convert.ToDouble(quantitySelect); sodaQuantity += (int)qsoda; Console.WriteLine("Press y if that is all for today"); string yesNo = Console.ReadLine(); if (yesNo == "n") continue;
if (yesNo == "y") { Console.WriteLine("Your total is $" + sodaQuantity*vendingOne); Console.WriteLine(); break; }

wiil be more readable as i get, u need program which works till u press "Y" ?

Adrian MT•9mo ago

Yes. How do I do what you did? Give me one sec

wwww•9mo ago

so like, u started it, when u pick option, it asks to pick option again, but if u press Y, it calculates all prices and maybe prints it

so, i see bit from txt file, there is a bit different logic, how do u solve it, depends on what specifically u want to do

Have you learned about methods yet?

Hazel 🌊💃•9mo ago

Also, my inference from your problem statement is that the user should be capable of selecting more than one item and calculate a total at the end, is that correct?

Adrian MT•9mo ago

Yeah! That's what I'm having trouble with

Hazel 🌊💃•9mo ago

Okay So Your totals shouldn't be at the top They should be after your loop is done

double quanity = 0;
double price = 1.325;
while (true) {
    quantity++;
    double currentTotal = quantity * price;
    Console.WriteLine("Added a soda, you now have " + quantity + " for a total of $" + currentTotal + ". ");
    Console.Write("Send 's' to stop. ");
    string response = Console.ReadLine();
    if (response == "s")
        break;
}

double total = quantity * price;
Console.WriteLine("Thanks! That'll be $" + total + ".");

double quanity = 0;
double price = 1.325;
while (true) {
    quantity++;
    double currentTotal = quantity * price;
    Console.WriteLine("Added a soda, you now have " + quantity + " for a total of $" + currentTotal + ". ");
    Console.Write("Send 's' to stop. ");
    string response = Console.ReadLine();
    if (response == "s")
        break;
}

double total = quantity * price;
Console.WriteLine("Thanks! That'll be $" + total + ".");

Calculate the current total on the fly with each iteration and save the final calculation for after the fact. Does that help?

Adrian MT•9mo ago

I think so, I'm looking at my code and this now, thank you!

wwww•9mo ago

also, if u leaned switch before, use it instead of multiple if statements with same logic so, there might be some things u don't know yet, but i think ull get it, happy to explain if need something to clarify @Aquaholic

static void Main(string[] args)
{
    const decimal SODA_PRICE = 1, COOKIE_PRICE = 2, CHIPS_PRICE = 1.5M;
    int sodaSold = 0, cookieSold = 0, chipsSold = 0;

    bool pepsi = true;
    while (pepsi)
    {
        Console.Clear();
        Console.WriteLine($"OSU Snacks menu\n" +
            $"Select 1 for Soda -->  price = ${SODA_PRICE}\n" +
            $"Select 2 for Soda -->  price = ${COOKIE_PRICE}\n" +
            $"Select 3 for Soda -->  price = ${CHIPS_PRICE}\n" +
            $"Or press Y to exit");

        string? userInput = Console.ReadLine();

        switch (userInput)
        {
            case "1":
                sodaSold++;
                break;
            case "2":
                cookieSold++;
                break;
            case "3":
                chipsSold++;
                break;
            case "Y":
                pepsi = false;
                break;
        }
    }

    decimal totalSum = (sodaSold * SODA_PRICE) + (cookieSold * COOKIE_PRICE) + (chipsSold * CHIPS_PRICE);
    Console.Clear();
    Console.WriteLine($"Total is: ${totalSum}");
}

            $"Or press Y to exit");

        string? userInput = Console.ReadLine();

        {
            case "1":
                sodaSold++;
                break;

    }

    decimal totalSum = (sodaSold * SODA_PRICE) + (cookieSold * COOKIE_PRICE) + (chipsSold * CHIPS_PRICE);
    Console.Clear();
    Console.WriteLine($"Total is: ${totalSum}");
}

I'm still learning quite a bit! We've really only had 5 modules of into to work with! I really do appreciate your help 🙂

Hazel 🌊💃•9mo ago

I'd stick with what you know and focus on the logic then as that's like the intent of your assignment 🙂 Best of luck!
