Question

Write the program in C++

The Rebel food truck has asked you to write a program for them to do both inventory and sales for their food wagon. Ben and Dave run the food truck and they already have full time day jobs so they could really use your help.

The food truck sells: hamburger, hotdogs, chilli, fries and soda. The truck has spots for 200 hamburger patties, 200 hot dogs, 75 hamburger buns, 75 hot dog buns, 500 ounces of chili, 75 fry baskets and 200 cans of soda.

Items sells for: Hamburger - $5, Hotdogs - $5, Chili (12 oz.) - $4, Fries (basket) - $7, Chili on burger, dog or fries (4 oz) - $2, Soda - $2. There is 5% tax in the area.

Create a menu driven program that they can run at the top of the night, put in current inventory and then sell items allowing them to enter sales for a customer on a repeating basis and get a result to charge them. Also take the items out of inventory when they are used. If an item goes to near zero and can no longer be sold then it should come off the menu.

Have something in the program that allows the user to terminate the program at the end of the night and it should signal to them if inventory for an item goes below 20%.

Answer 1

#include<iostream>
using namespace std;
int main()
{
    //inititalize the items
    string items[7]={"Hamburger Patties","Hamburger Buns","Hot Dogs","Hot Dog Buns","Chilli","Fry Baskets","Soda"};
    //initialize the quantity
   static int nos[7]={200,75,200,75,500,75,200};
   //initialize the price
    int price[7]={5,5,5,5,4,7,2};
    //initialize the twenty percentage of items
    int twentypercen[7]={40,15,40,15,100,15,40};
    int i,j,k,total=0,n;
    char opt;
    //infinite loop
    while(1)

   //display the items
       for(i=0;i<7;i++)
       {//check the status of items whether 0 or not, if 0 then discard it from menu
           if(nos[i]!=0)
           {

           else
           {
              top:

           {
              cout<<endl<<items[k-1]<<"can be taken out multiple of 12";
              goto top;
           }
           //compute the total
           total=total + price[k-1]*(n/12);
           //update the quantity
       nos[k-1]=nos[k-1]-n;
           }
           }

//block for other items
           else
           {
              //ask for the quantity
              cout<<endl<<"Enter the quantity of "<<items[k-1];
               cin>>n;
               //compute the total
               total=total + price[k-1]*n;
               //update the quantity
       nos[k-1]=nos[k-1]-n;
           }
           //display the items below 20%
       for(i=0;i<7;i++)
       {
           if(nos[i]<twentypercen[i])
           cout<<endl<<items[i]<<" goes below 20%";
       }
       //ask user to continue or not
       cout<<endl<<"Do you want to continue(y/n)";
       cin>>opt;
       if(opt=='n'||opt=='N')
       break;
         
   }
   //display the total
   cout<<endl<<"Total Amount to pay : $"<<total;
}

output
