What I Have so far:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main () {
string line;
int numPeople = 0;
string person;
string arrPeople[20];
string tempString;
ifstream peopleIn;
string addPeople;
ifstream myfile (\"a1.txt\");
if (myfile.is_open())
{
while ( getline (myfile,line) )
{
cout << line << \'\ \';
getline(peopleIn, tempString, \',\');
getline(peopleIn, tempString, \' \');
getline(peopleIn, tempString, \' \');
getline(peopleIn, tempString, \' \');
getline(peopleIn, tempString, \'\ \');
arrPeople[numPeople] = person;
++numPeople;
}
while (1)
{
cout << \"Do you want to add another person (y or n): \";
cin >> addPeople;
if (addPeople == \"n\")
break;
cout << \"Enter Last Name: \";
cin >> tempString; // put the data in structure or class
cout << \"Enter First Name: \";
cin >> tempString; //put the data in your structure or class

cout << \"Enter SSN: \";
cin >> tempString; //put the data in your structure or class

cout << \"Enter Address: \";
cin >> tempString; //put the data in your structure or class

cin.ignore(100, \'\ \'); // you may need this to clear the input buffer after entering the address
}
myfile.close();
}

else cout << \"Unable to open file\";

return 0;
}

Trying to make it so i can ask the user if they wish to add another name they hit y or n for yes or no, then change the list like the list above including anything the user puts in. I always seem to have a hard time finding where things are located to manipulate them

Solution

#include<iostream>

#include<string>

using namespace std;
int main () {
string line;
int numPeople = 0;
string person;
string arrPeople[20];
string tempString;
ifstream peopleIn;
string addPeople;
ifstream myfile (\"a1.txt\");
  
int levels[20];
char p[300];
char arr[100];
int j=0;
if (myfile.is_open())
{
   cout << \"\ People before sorting \ \";
while ( getline (myfile,line) )
{
cout << line << \'\ \';
  
std::strcpy(p, line.c_str());
  
for(int i=0; i<200;i++) // extract the integer value after first space
{
   j=0;
       if(p[i]==\' \')
       {
           i++;
           while(p[i]!=\' \') // read all the numbericals upto space
           {
               arr[j]=p[i];
               j++; i++;
           }
           levels[numPeople]=atoi(arr); // store this value in number array
           break;
}
   }
  
    arrPeople[numPeople] = line;
    ++numPeople;
}
  
// sort the number array and make swaps on both number array as well as string aray
for(int z=0;z<numPeople;z++)
       for(int k=z;k<numPeople;k++)
       {
           if(levels[z]>levels[k])
           {
               j=levels[z];
               levels[z]=levels[k];
               levels[k]=j;
               person=arrPeople[z];
               arrPeople[z]=arrPeople[k];
               arrPeople[k]=person;
           }
       }
  
   cout << \"\ People after sorting \ \";
   for(int z=0;z<numPeople;z++)
       cout <<arrPeople[z]<< \" \"<<levels[z]<<endl;
  
myfile.close();
}
else cout << \"Unable to open file\";
return 0;
}
