Can you help me fix this code? Im getting 2 errors.1 says expression must be a modifiable value. the second says 'index' you cannot assign to a variable this is const. Both are on line 42. Thank you

Write a program that uses a dynamic list of strings to keep track of a list of chores that you have to accomplish today. The user of the program can request several services: (1) Add an item to the list of chores; (2) Ask how many chores are in the list; (3) Have the list of chores printed to the screen; (4) Delete an item from the list; (5) Exit the program. If you know how to read and write strings from a file, then have the program obtain its initial list of chores from a file. When the program ends, it should write all unfinished chores back to this file.

Write a program for problem 5 in chapter 4.

Use appropriate private data members and provide a public interface for each class that satisfies the description given in the book.

#include <iostream>
#include <sstream>
#include <string>
using namespace std;
int main()
{
int index = 5;
int head = 0;
string s[index];
int flag = 1;
int choice;
while (flag)
{
cout << "\n1. Add an Item in the Chores List.";
cout << "\n2. How many Chores are in the list.";
cout << "\n3. Show the list of Chores.";
cout << "\n4. Delete an Item from the Chores List.";
cout << "\n5. Exit.";
cout << "\n\nEnter your choice : ";
cin >> choice;
switch (choice)
{
case 1:
{
string str;
if (head < index)
{
cout << "Enter strings : ";
cin >> str;
s[head] = str;
head++;
}
else
{
index = index * 2;
string temp[index];
for (int i = 0; i<head; i++)
temp[i] = s[i];
//s = temp;
s[head] = str;
head++;
}
break;
}
case 2:
{
cout << "\nThe total number of items in the list is : " << head << "\n";
break;
}
case 3:
{
for (int i = 0; i<head; i++)
cout << s[i] << "\n";
break;
}
case 4:
{
head--;
s[head] = "NULL";
break;
}
case 5:
{
flag = 0;
break;
}
default:
{
cout << "\nWrong entry. Please try again.\n";
break;
}
}
}
return 0;
}

OUTPUT:
