Create a program that makes a grocery list.

You will need an array of strings.

You don’t know how many items will be on your list.

Simple problem: User tells you how many items, then tells you the items. You display the items for the user.

More complex problem: User tells you how many items, then tells you the items.

You display the items for the user. At the end of the program, write the grocery list to a text file called grocery.txt.

Even more complex problem: If grocery.txt exists, read it into an array and display to the user.

User then tells you how many more items, and then tells you the items. You display all the items for the user.

At the end of the program, write the grocery list to a text file called grocery.txt.

Start with the simple program, move toward the complex one.

//1st problem

#include<iostream>
#include<fstream>
#include<string>
//define MAX items in list
#define MAX 1000
using namespace std;
//function to print the item list
void print(string s[], int n);
//declare function read text file
int read_grocery_text(string s[], int &n);

int main()
{
string items[MAX];
int n,more_items = 0;

//function definitin for displaying item list
void print(string s[],int n)
{
   cout << \"\ Display items: \" << endl;
   for (int i = 0; i < n; i++)
   {
       cout << i+1<<\". \" << s[i] << endl;
   }

}

//problem2

int main()
{
string items[MAX];
int n,more_items = 0;

   cout << \"Enter number of items: \";
   cin >> n;
   cin.ignore();
   //ask the user about each item name
   for (int i = 0; i < n; i++)
   {
       cout << \"item\" << i + 1 << \" :\";
       getline(cin, items[i]);

   }

   print(items, n);
  ofstream out;
   //open Grocery file for writing
   out.open(\"Grocery.txt\");
   //check if file is open
   if (!out)
   {
       cout << \"file can\'t be open for writing\" << endl;
   }
   //write items to file
   for (int i = 0; i < n; i++)
   {
       out << items[i] << endl;
   }
   //out << EOF;
   out.close();
}

//function definitin for displaying item list
void print(string s[],int n)
{
   cout << \"\ Display items: \" << endl;
   for (int i = 0; i < n; i++)
   {
       cout << i+1<<\". \" << s[i] << endl;
   }

}

//proble3

int main()
{
string items[MAX];
int n,more_items = 0;

   //to read from file and store in array use below code
   int ret = read_grocery_text(items, n);
   cout << \"Enter number of more items: \";
   cin >> more_items;
       //ask the user about each item name
   cin.ignore();
   for (int i = n; i < n + more_items; i++)
   {
       cout << \"item\" << i + 1 << \" :\";
       getline(cin, items[i]);
   }

   print(items, n + more_items);

}

int read_grocery_text(string s[], int &n)
{
   ifstream in;
   //declare a variable to hold number of items
   int count = 0;
   //open input file grocery.txt
   in.open(\"Grocery.txt\");
   //check if file can be open
   if (!in)
   {
       cout << \"file can\'t be open for reading\" << endl;
       return -1;
   }
   while (!in.eof())
   {
       getline(in, s[count]);

       if (in.eof())
           break;
       ++count;
   }
   n = count;
   return 0;
}
