Question 4. Write a program to help a local restaurant automate its breakfast billing
system. The program should do the following:
a. Show the customer the different breakfast items offered by the restaurant.
b. Allow the customer to select more than one item from the menu.
c. Calculate and print the bill.
Assume that the restaurant offers the following breakfast items (the price
of each item is shown to the right of the item):
Plain Egg $1.45
Bacon and Egg $2.45
Muffin $0.99
French Toast $1.99
Fruit Basket $2.49
Cereal $0.69
Coffee $0.50
Tea $0.75
Your program must contain at least the
following functions:
Explanation / Answer
#include <iostream>
#include <fstream>
#include <cstring>
#include <string>
using namespace std;
struct menuItem
{
string item;
float price;
int quantity;
};
menuItem* breakfastMenu = new menuItem[8];
void getData()
{
ifstream myfile ("Ch9_Ex4Data.txt");
if (myfile.is_open())
{
string line;
int i=0,flag=1;
while ( getline (myfile,line) )
{
if(flag){
breakfastMenu[i].item = line;
flag=0;
}
else{
breakfastMenu[i++].price = atof(line.c_str());
flag=1;
}
}
}
else cout << "Unable to open file";
myfile.close();
}
void printCheck()
{
float billAmount;
for(int i=0;i<8;i++)
{
if(breakfastMenu[i].quantity > 0)
{
billAmount += breakfastMenu[i].quantity * breakfastMenu[i].price; //cout statement can't output assignement
cout<<billAmount<<endl;
}
}
cout<<"Amount Due $"<< billAmount<<endl;
}
void showMenu()
{
int num,quantity;
char c;
for(int i=0;i<8;i++)
cout<<(i+1) <<". " < cout<<"What would you like to have?";
cin>>num;
cout<<"Quantity?"< cin>>quantity;
breakfastMenu[num-1].quantity = quantity;
cout<<"Print check?(y/n)"< cin>> c;
if(c=='Y' || c=='y')
printCheck();
else
showMenu();
}
int main()
{
getData();
showMenu();
system("pause");
return 0;
}
