std::list - cppreference.com (original) (raw)

std::list is a container that supports constant time insertion and removal of elements from anywhere in the container. Fast random access is not supported. It is usually implemented as a doubly-linked list. Compared to std::forward_list this container provides bidirectional iteration capability while being less space efficient.

Adding, removing and moving the elements within the list or across several lists does not invalidate the iterators or references. An iterator is invalidated only when the corresponding element is deleted.

std::list meets the requirements of Container, AllocatorAwareContainer, SequenceContainer and ReversibleContainer.

[edit] Example

#include #include #include   int main() { // Create a list containing integers std::list l = {7, 5, 16, 8};   // Add an integer to the front of the list l.push_front(25); // Add an integer to the back of the list l.push_back(13);   // Insert an integer before 16 by searching auto it = std::find(l.begin(), l.end(), 16); if (it != l.end()) l.insert(it, 42);   // Print out the list std::cout << "l = { "; for (int n : l) std::cout << n << ", "; std::cout << "};\n"; }

Output:

l = { 25, 7, 5, 42, 16, 8, 13, };
