The List get method is a built-in method provided by the C++ Standard Template Library (STL). It is used to retrieve the element at a given position in a doubly linked list.

Here is an example code snippet:

#include 
#include 
using namespace std;

int main() {
    // create a list
    list mylist{10, 20, 30, 40, 50};

    // get element at position 2
    auto it = next(mylist.begin(), 2);
    int val = *it;

    // print the value
    cout << "Value at position 2: " << val << endl;

    return 0;
}

In this example, we create a list of integers (10, 20, 30, 40, 50) and retrieve the element at position 2 (which is 30). We use the `next()` method, which returns an iterator to the element that is n positions away from the iterator passed to it. We then dereference the iterator to get the actual value. The `list` and `next` methods are part of the STL library in C++.
