Homework SourseHelp with the following code 1 Rewrite to be contained in a
Help with the following code:
1. Rewrite to be contained in a vector object.
2. Using linked lists, redo to handle as many entries as required.
3. Add the ability to add or delete a new entry to the address book.
4. When the program terminates, write the data in the address book to a disk.

Solution
Question 1
Changes to be made in the code:
Instead of:
char name[500];
write:
vector<char> name(500);
similarly, instead of:
char address[500];
change it to:
vector<char> address(500);
and finally change
addressbook book[10];
to:
vector<char> book(10);
You might have figured it out by the changes but for reference, changing an array to vector has to be done by mentioning \"vector\" followed by the \"data_type\" inside \"<>\" and then mentioning the name of the identifier(variable) like in an array and providing its size, but the size has to be inside \"()\" instead of \"[]\".
Edit1- include the vector header file at the header section as:
#include<vector>
Here is the complete code-
# include <iostream>
# include <conio.h>
# include <stdio.h>
#include <vector>
using namespace std;
