Access an object stored in the list.

[cbarmpar]

Hi all,

I am storing some objects in the list and the i am trying to access them one by one. Each object consists of two strings and one integer.

The problem is that i cannot access these objects through the iterator.
1.How can i access these objects?

#include <stdlib.h>
#include <iostream>
#include <map>
#include <list>
using namespace std;
 
 
class A{
public:
    string x;
    string y;
    int z;
};
 
list<A> G_QUERY_LIST;
list<A>::iterator it;
 
 
void create_new_query()
{
    string name;
    string query;
    string results;
    cout << "Please enter a name for this query: ";
    cin >> name;
    cout << "Please enter the query you want to execute: ";
    cin >> query;
    A ena;
    ena.x = name;
    ena.y = query;
    G_QUERY_LIST.push_back(ena);
}
 
 
int main() {
  create_new_query();
  create_new_query();
  cout << "mylist contains:";
  for (it=G_QUERY_LIST.begin(); it!=G_QUERY_LIST.end(); it++)
  cout<< *it.ena.x;
  cout << endl;
 
 
 
  return 0;
 
}

#include <stdlib.h>
#include <iostream>
#include <map>
#include <list>
using namespace std;


class A{
public:
    string x;
    string y;
    int z;
};

list<A> G_QUERY_LIST;
list<A>::iterator it;


void create_new_query()
{
    string name;
    string query;
    string results;
    cout << "Please enter a name for this query: ";
    cin >> name;
    cout << "Please enter the query you want to execute: ";
    cin >> query;
    A ena;
    ena.x = name;
    ena.y = query;
    G_QUERY_LIST.push_back(ena);
}


int main() {
  create_new_query();
  create_new_query();
  cout << "mylist contains:";
  for (it=G_QUERY_LIST.begin(); it!=G_QUERY_LIST.end(); it++)
  cout<< *it.ena.x;
  cout << endl;

  

  return 0;

}

Many thanks in advance.

for (it=G_QUERY_LIST.begin(); it!=G_QUERY_LIST.end(); ++it)
  cout<< (*it).ena.x;

for (it=G_QUERY_LIST.begin(); it!=G_QUERY_LIST.end(); ++it)
  cout<< (*it).ena.x;

Priority of * is lower than that of "."

FYI: Note that, generally, ++it is faster for iterators.

PS: If you do not mind using 3rd party libs: using Boost.Foreach your code could be written

#include <boost/foreach.hpp>
BOOST_FOREACH(const A &item, G_QUERY_LIST)
  cout<< item.ena.x;

#include <boost/foreach.hpp>
BOOST_FOREACH(const A &item, G_QUERY_LIST)
  cout<< item.ena.x;

Excellent answer thats what i wanted!

A small correction:
its (*it).x and not (*it).ena.x
