#include <iostream>
#include <vector>

using namespace std;
void temp( vector<string> * temp);


int main()
{
    vector<string> idVector;  
    temp(&idVector);
    cout<<idVector[0] << endl;
    cout<<idVector[1];
    return 0;
}

void temp( vector<string> * temp){
      temp->push_back("hello");     //normally without pointers,  temp.push_back("hello"), but arrow will dereference and accessing the member
      temp->push_back("bigboi");
