How to call items to print receipt

Hi, I dont know how to do this part and according to all posts and codes I read, the code does not store how many I've ordered, and it just shows the total price.

The end goal is to be able to print the individual orders, quantity, and price then its total.
It would look like this:

Order Quantity Price

Breakfast Burrito 2 460

Blueberry Pancakes 1 180

Total 640

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <conio.h>


 
//void (for menu) declarations
void Menu (void);
void Options (void);

void OptionsGoingToReceipt (void);
void Receipt (void);

Any inputs will be appreciated, thanks in advance

First of All, your code is amazing. It seems you did put a lot of efforts into it.

The menu which you printed in print statement could be stored in a multidimensional String array, and can be printed using a loop.
Here I didn't wanted to do all that storing the menu in an array, that's too hectic.
What I did is used an array to store the Order.
It's like a 20 by 3 table, 20 rows as your menu has max 20 items.
3 columns are for Menu code, quantity, Subtotal respectively.

Also note that , you didn't put a default condition in Switch statement, if someone enters menu code that doesnot exist then
it must prompt for for Wrong option and ask for menu code again.

so here is my code(Honestly it's your's , I just did some changes):

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <conio.h>






//void (for menu) declarations

    printf("\n*************************************");
    printf("\nEnter your username: ");
    scanf("%s",username);

I don't suppose you've come across things like
- arrays
- structures
- loops

Things that would greatly simplify your code.

> First of All, your code is amazing. It seems you did put a lot of efforts into it.

Sorry to say but the code is horrible. You probably haven't experienced what good, neat code looks like :p
About the efforts: yeah, they are a lot, but not required tbh. This can be made much much much simpler.

Hellooo sorry late reply but thanks so much!!! You placed a lot of effort as well. I copied your code but this part had an error so I fixed it already. I read your feedback and learned a lot from it so thanks again, really appreciate it.


The error:

Code:

---

for(int i=0;i<orders;i++)

---

Got fixed though so here:

Code:

---

int i=0;//void Receipt
void Receipt (void)
{
    printf("\n========================================================================================");
    printf ("\n\t                SUNNY BREAKFAST HUB Receipt");
    printf("\n========================================================================================");
    printf("\n  Order\t    Quantity\tPrice\n(Menu Code)\n");
    for( i=0;i<orders;i++)
        printf("\n  %d\t\t    %d\t\t%d",order[i][0],order[i][1],order[i][2]);
    printf("\nTotal Price: %.2f",TotalPrice);
    GoingDiscounts();
}


void GoingDiscounts (void)
{
printf ("\n\t                Would you like a discount?");
printf ("\n\n001    None ");
printf ("\n002    Senior (20%)");
printf ("\n003    Others (30%)");
InputGoingDiscountsAgain:
printf ("\n\nEnter the Discount Code here: ");
scanf ("%i", &discount);

---

This is the final output btw:

Thanks for the input, I dont know much in arrays and structures, but will try to understand how they work.

Sorry to say but the code is horrible. You probably haven't experienced what good, neat code looks like :p
About the efforts: yeah, they are a lot, but not required tbh. This can be made much much much simpler.

Well for sure there is a better way but hopefully I get to learn more, thanks.

Some points to bear in mind.

1. By convention (and because that's how it works), newlines go at the end of the string being output, not at the start.
This is because when stdout is a terminal, the stream is typically line buffered, which means it gets flushed with every \n
In short, printf("hello\n") has a much better chance of being seen than printf("\nhello").

2. else if (OptionReceipt != 001 || OptionReceipt != 002 || OptionReceipt != 003)
Beware that numeric constants with a leading zero indicate base 8 (octal) to the compiler, not base 10.
You're fine up to 007 (Mr Bond), but try writing 008 and you're in for surprises.

Oh, and before you copy/paste your way to another 1000 line program, here is something to study, and hopefully inspire you.

Woahhhh, thanks so much for the lesson! I'm definitely learning more here compared to class. I'll bear these in mind, and I just can't stop looking at how short it could possibly be. Now I know what I should aim for. Thanks again.

P.S.: I won't use this for submission, but this is definitely something I can check on when I need a reference in future projects.
