I have a list iterator that goes through a list and removes all the even numbers. I can use the list iterator to print out the numbers fine but I cannot use the list's remove() and pass in the dereferenced iterator.

I noticed that when the remove() statement is in effect, *itr gets corrupted? Can somebody explain this?

#include <iostream>
#include <list>

#define MAX 100

using namespace std;

int main()
{
    list<int> listA;
    list<int>::iterator itr;

    //create list of 0 to 100
    for(int i=0; i<=MAX; i++)
        listA.push_back(i);

    //remove even numbers
    for(itr = listA.begin(); itr != listA.end(); ++itr)
    {
        if ( *itr % 2 == 0 )
        {
            cout << *itr << endl;
            listA.remove(*itr);    //comment this line out and it will print properly
        }
    }
}
