Menu Driven Program
Hi,
I have managed to get my program to work, and it looks great. But the output is not exactly what I want. In the print function, the loop seems to be repeating some items. This shouldn't be the case. This is my first time here, but I will appreciate any help. Thanks in advanced.
[This is my code]
//Assignment IV- Restaurant Menu: Nathaniel Cooper; Nov. 8, 2015
//This program automate the breakfast billing system of Cooper's restaurant.
#include<iostream>
#include<string>
#include<iomanip>
using namespace std;
struct ItemType //Struct Declaration
{
string item_name;
double UnitPrice;
};
//Functions Prototypes
void showMenu(ItemType MenuList[],int s);
int getData(ItemType MenuList[], ItemType OrderedList[], int Max);
void printCheck(ItemType OrderedList[], int counter);
int main()
{
int counter = 0;
const int SIZE = 8;
const int Max = 30;
ItemType OrderedList[Max];
ItemType MenuList[SIZE] = {{"Plain Egg", 1.45}, {"Bacon & Egg", 2.45 }, {"Muffin", 2.45},
{"French Toast", 1.99}, {"Fruit Basket", 2.49}, {"Cereal", 0.69},
{"Coffee", 0.50}, {"Tea ", 0.75}};
//Functions Call
showMenu(MenuList,SIZE);
counter = getData(MenuList, OrderedList, Max);
printCheck(OrderedList, counter);
return 0;
}
void showMenu(ItemType MenuList[], int s)
{
cout << "Welcome to Cooper's Restaurant!! \n";
cout << "The Citadel of Delicious Food. \n\n";
cout << " Items " << setw(25) << "Unit Price \n";
for(int count = 0; count < s; count++)
{
cout << "#" << count+1 <<" "

}
cout << "\nEnter the number of your selection until you have completed your order. \n";

}
int getData(ItemType MenuList[], ItemType OrderedList[], int Max)
{
int choice;
int counter = 0;
do{
cout << "What would you like? If you done ordering (enter 9): \n";
cin >> choice;
if(choice < 1 || choice > 9)
{
cout << "\a\a Invalid Input \n";
cout << "Enter the number of your selection. \n";
cin >> choice;
}
if(choice !=9)
OrderedList[counter].item_name = MenuList[choice-1].item_name; //enters item name in order
OrderedList[counter].UnitPrice = MenuList[choice-1].UnitPrice; //enter price in order
counter++;
}while(choice !=9 && counter < Max); //repeats the whole thing until 9 is entered
return counter;
}
void printCheck(ItemType OrderedList[],int counter)
{
double tax = 0.05;
double checkTotal;
double FinalTotal;
cout << "\nWelcome to Cooper's Restaurant!"<< "\n";
cout << "This is your check. \n\n";
cout << "***************************************************** \n";
for(int count = 0; count < counter; count++)
{
cout << " "
<< OrderedList[count].item_name <<"\t\t$"
<< OrderedList[count].UnitPrice << "\n";
checkTotal += OrderedList[count].UnitPrice;
}
tax = checkTotal * tax;
FinalTotal = checkTotal + tax;
cout << setw(25) << left << "Tax" <<fixed << showpoint <<setprecision(2)<<"$"<<tax << "\n";
cout << "***************************************************** \n";
cout << setw(25) << left << "Total" <<fixed << showpoint <<setprecision(2)<<"$"<<FinalTotal << "\n";
}
*You will fully understand my point if you run the code. I just can't find why it's not doing what I want it to do.

Look at this snippet:
Do you realize that arrays start at zero, not one?

What exactly do you want it to do?

Please edit your first post to add the code tags (The <> icon to the right).
I edited it. I also did the 'add the code tag.' I don't know if this makes sense, in the print function, the loop repeats the first item twice. This shouldn't be the case.
I want to print out the items, but I don't want any items to be repeated.
Those this make sense?

Please, use code tags (the <> formatting button) when posting code.
It makes it easier to read your code and also easier to respond to your
post.

The problem is in the function getData().
counter gets incremented once to often and then of course in printCheck it will print one item to much.
There is also a small problem with the alignment of the output.
