Can someone help me alter this code to accept input from the user, output any changes to a separate text document, titled information.txt, and allow the user to do everything that the skeleton menu indicates? Any and all help is appreciated.

PROGRAM CODE:

Main.cpp

#include <iostream>
using namespace std;

int menu();
int find(vector<Person>, string);
//function to update the data to file every time
void writeToFile(ofstream& , vector<Person>);

int main() {
// Container for holding all Person objects.
vector<Person> people;
ofstream out("information.txt");
while(true)
{
int choice = menu();
PersonDetails p;
string name;
int index;
switch(choice)
{
    case 1: cout<<"Enter name: ";
            cin>>p.name;
            cout<<" Enter phone: ";
            cin>>p.phone;
            cout<<" Enter address: ";
            cin>>p.address;

}
}
return -1;
}

void writeToFile(ofstream& out, vector<Person> people)
