Trouble with lists

[blueeyedlion]

This is my program:

#include <iostream>
#include <list>

int main ()
{
    std::list<int> intList {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

    for (auto iter = intList.begin (); iter != intList.end (); ++iter)
    {
        if (*iter == 5)
        {
            intList.erase (iter);
        }
        
        std::cout << *iter << std::endl;
    }
    
    int x;
    std::cin >> x;
    
    return 0;
}

From what I understand, it should output:

1
2
3
4
6
7
8
9
10

Instead, it seems to miss the end of the list and keeps outputting large numbers extremely quickly. What did I do wrong?

You shall write

iter = intList.erase (iter);


Or you can use member function remove . For example

std::list<int> intList {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

intList.remove( 5 );
