❔ 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 Marquez TrevizoOP•2y ago

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

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?

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 Marquez TrevizoOP•2y ago

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

tacosontitan•2y 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 Marquez TrevizoOP•2y ago

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

xdd•2y 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;

                chipsSold++;
                break;

                pepsi = false;
                break;
        }
    }

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

        string? userInput = Console.ReadLine();

    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 🙂

tacosontitan•2y 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!
