help, please....

I'm supposed to write a program with the following information, but I'm not exactully sure how because of poor examples from my source books. im supposed to use loops



You will have 3 functions in addition to the main function
Get_list will print the list for the user and get the input from the user
Total_cost will calculate the total cost of the items
Take_money will print the bill, get the debit input from the user and print the change. Use an error trap so that a debit of more than $20.00 over the bill or a debit less than the bill will not be accepted.

You will need to use the following constants
MILKPRICE = 1.37
EGGPRICE = 1.29
BREADPRICE = .88

Code:

---

Here is your main function. You must use this in your program - do not change it.

//=============================main=============
int main()
{ int eggs, milk, bread;// entered by user
float bill;// calculated

Get_list(eggs, milk, bread);
bill = Total_cost(eggs,milk,bread);
Take_money(bill);

return 0;
}// end main

---

****edit***opps, sorry...i forgot to add what i had come up with so far. i'm sorry, i wouldn't want to do someone one elses homework either**

Code:

---


#include <iostream.h>

 


//=============================main========================
int main() 

{ int eggs, milk, bread;// entered by user
float bill;// calculated

egg=milk=bread=0;
bill= 0.0;               



Get_list(eggs, milk, bread);
bill = Total_cost(eggs,milk,bread);
Take_money(bill);

return 0;
}// end main 

const double MILKPRICE = 1.37, EGGPRICE = 1.29, BREADPRICE = 0.88


///==================Get_list========= 
void Get_list()
{
  cout<< " Please enter the number or items you would like"<<endl; 
 
  cout<< " How many quarts of milk @ $1.37 :  "<<endl;
  cin>> milk;
 
  cout<< " How many dozens of eggs @ $1.29 : "<<endl;
  cin >> eggs;   
 
  cout<< " How many loaves of bread @ $0.88 : " << endl;
  cin >> bread;

} //end get_list


//==========Total_cost==========
 {
Total_cost= MILKPRICE * milk + EGGPRICE * eggs + BREADPRICE * bread
 } // end Total_cost
 
 
 //==========Take_money=====
 {
  cout<<"Your total bill is: "<<bill<<endl; 
 
  cout<<"Please enter the amount you want debited:"<<endl;
  cin>>Take_money;
 
  if(Take_money >50)
          {
                  cout<<"Sorry, you have a limit of $20.00 over your bill." << endl;
                  cout<< Your maimum debit can be" << bill + 20<< endl;
                  cout<< "Please reenter your debit amount:<<endl;
          } 
         
         
  }//end Take_money

We're not going to do your homework for you. At least start it and post what you get. We'll help you fix it up if it's still not working.

Code:

---

#include <iostream>

const double MILKPRICE = 1.37,EGGPRICE = 1.29,BREADPRICE = 0.88;

class menu
{
        int egg, milk, bread;
        double total;
       

public:
        menu();
       
        void get_list();
        double total_cost();
        void debit_bill();
};


menu::menu()
{
        egg = milk = bread = 0;
        total = 0.0;
}


void menu::get_list()
{
        std::cout << "Enter the no: of eggs (0 if not needed)";
        std::cin >> egg;

        std::cout << "Enter the no: of liters of milk (0 if not needed)";
        std::cin >> milk;

        std::cout << "Enter the loaves of bread (0 if not needed)";
        std::cin >> bread;
}

double menu::total_cost()
{
        total = MILKPRICE * milk + EGGPRICE * egg + BREADPRICE * bread;
        return total;
}

void menu::debit_bill()
{
        std::cout << "Item\t\tQuantity\t\tPrice" << std::endl;
        std::cout << "Egg \t\t" << egg << "\t\t\t" << EGGPRICE * egg << std::endl;
        std::cout << "Milk\t\t" << milk << "\t\t\t" << MILKPRICE * milk << std::endl;               
        std::cout << "Bread\t\t" << milk << "\t\t\t" << BREADPRICE * bread << std::endl;
        std::cout << "Total\t\t\t\t\t" << total <<std::endl;
        double cash_accept;

        std::cout << "Enter the amount given by the customer" << std::endl;
        std::cin >> cash_accept;

        if(cash_accept < total)
        {
                std::cout << "Pay up buddy.. no credit accepted" << std::endl;
        }
        else
        {
                std::cout << "You have been kind... i will keep the change" << std::endl;
        }
}


int main()
{
        menu m1;

        m1.get_list();
        m1.total_cost();
        m1.debit_bill();

        return 0;
}
