I need some help with my project

[ChrizWar]

I'd like to ask some professionals who can help me with a program project. For example, ATM machine program. But mine isn't actually an ATM program, I am just stuck on my code so I need someone to help me with this. I'll send the code to you if you are confident to help me on this, I'm willing to spend all my time for this project. Anyone who wants to help?

I suggest you post the code, inside of code tags, and then ask specific questions about your code. I doubt you'll get too many people to give you free one on one tutoring here.

@jlb, this is my code: http://pastebin.com/YJp7hzVn

I can't seem to work on the loop for case 1. So I tried to put a "goto".

Rule:

In case 1: at the if-else statment:

Would you like to try another transaction? [y/n]

If yes, it will go outside the loop and try another type of transaction.
If no, it should continue the CURRENT transaction unless your choice changes to a "yes".

Your code isn't very long it would have been better to post it inline:

	

    #include <iostream>
    #include <conio.h>
    #include <string.h>
    using namespace std;

    };
     
    Item inventory[] = {                        // Each product has 100 stocks.
        { 100, "Bottled Water" },
        { 100, "Bottled Juice" },

        { 100, "Iced Tea" },

            else if (answer == 'n')
            {
             cout << "Transaction finished.";    
            }
            break;
           
        case 2:
           
            cout << "NORMAL TRANSACTION\n";
            getSale(prod, quantity, price);
            total_sale = quantity * price;
            cout << "\nTotal product to be sold: " << quantity;
            cout << "\n\nTotal price = %.2f" << total_sale;
            reportInventory(prod);
            break;
        }
        getch();
    }

Now you need to ask specific questions based on that code.

Also I suggest you stop using the goto, use one of the other more accepted loops instead.

Sorry, it's because I haven't done all the cases. I will need case 4 and 5 for tables to monitor the stocks deducted, sold, and the available stocks for EACH product. Can you help me finish it.

[ChrizWar]

The code you posted doesn't seem to work, though...

[jlb]

That's your code, I just copied it from your link.

Why are you mixing C-stdio functions and C++ streams? This is C++ so stick with the C++ streams.
