Turn order into bill C++

[yue219]

Language is C++.
I dont know how to take what the user orders and calculate their bill. I used a class. Heres my code:

#include <iostream>
#include <string>
#include "Headerfile.h"
using namespace std;
 
int main ()
{ 
    //This prints out the menu 
    Menu ChoosingAnItem;
    ChoosingAnItem.menu();
 
    //This asks the user what they would like to order
    Menu ORDERING;
    ORDERING.ordering();
 
    struct Something {item, status, price}
 
 
    return 0;
}
 
//********************************************
Header File
//******************************************
#include <string>
#include <iostream>
using namespace std;
 
class Menu
{
    public:
        string menu();
        string ordering();
 
        string removing();
        string adding();
        string printing();
        float totalPrice();
        string testing();
 
    private:
        string test;
};
//*****************************************

#include <iostream>

//***********************
//This is the menu the user sees 
string Menu::menu()
{
    string MENU;
    printf ("        --Menu--\n\n");
    printf ("  *Main course:\n");
    printf ("  1. Tomato Brushetta\t\t6.29\n");
    printf ("  2. Calamri Fritti\t\t8.29\n");
    printf ("  3. Pesto Chicken Pizza\t9.99\n");
    printf ("  4. Chicken Florentine\t\t9.99\n");
    printf ("  5. Eggplant Parmesan\t\t10.29\n");
    printf ("  6. Penne Rusitca\t\t13.29\n");
    printf ("  7. Veal Marsal\t\t13.99\n");
    printf ("  8. Grilled Halibut\t\t16.99\n\n");
    printf ("  *Drinks:\n");
    printf ("  9. water\t\t\t2.00\n");
    printf ("  10. italian soda\t\t2.50\n");
    printf ("  11. wine\t\t\t7.50\n\n");
    return MENU;
};
//**********************
string Menu::ordering()
{
    string order;
    printf( "What would you like to order?\n" );
    return order;
};
//************************
string Menu::removing()
{
 
 
};

I think what im stuck on is how to put that menu in a array.

[sicarie]

Do you want to put the menu in an array, or do you want to receive an order? YOu asked two different questions there. The menu would go in an array of strings exactly as it is in your print statements now. You could remove the numbers and use the array index + 1 (which I would recommend so you don't have to worry about numbers getting out of order or needing to keep track of them), and then you could just print it out with a for loop.

as for ordering, right now you just say

string Menu::ordering()
{
    string order;
    printf( "What would you like to order?\n" );
    return order;
};
 

So you're not even reading anything in, you're just returning an empty string. I would recommend setting it up so that the user (waiter) puts in a number. You could have them type it in, but then you have to worry about cases and misspellings, etc... Then you can match the number with a menu option, or even a price if you put it in a map... That's sort of up to you.
