Can you explain C++11 std::list iterator examples?

Sure! In C++11, the std::list container provides iterators to traverse its elements. Would you like to see a specific example?

Yes, please show me how to use the iterator to print all elements in a std::list.

Here's a simple example:

#include <iostream>
#include <list>

int main() {
    std::list<int> myList = {1, 2, 3, 4, 5};
    for (auto it = myList.begin(); it != myList.end(); ++it) {
        std::cout << *it << " ";
    }
    return 0;
}

This code will print all elements in the list.

What if I want to remove an element while iterating?

You can use the erase method. Here's an example:

for (auto it = myList.begin(); it != myList.end(); ) {
    if (*it == 3) {
        it = myList.erase(it); // erase returns the next iterator
    } else {
        ++it;
    }
}

This will remove the element '3' from the list while iterating.
