Getting started with STL in C++. The Standard Template Library (STL) is a very useful set of template classes containing various containers. One among these containers is Lists. Today we’ll be having a look at Lists in STL. But before we proceed further I’d like to say that if this is your first time learning STL then I’d recommend you have a look at this article before beginning with this one.

With that being said let’s dive further into the topic by knowing what are lists in STL ?
Lists are a type of sequence containers which provides us with constant insertion and deletion time anywhere within the sequence given that we have obtained the corresponding iterator to the same. It also allows us traversal in both the directions.
List containers are implemented as doubly-linked lists. The memory management is done internally by maintaining a link to the previous as well as the next element in the sequence with respect to each element. A significant drawback of lists being that we don’t have direct access to the elements since it uses non contiguous memory allocation for each element in the sequence. Thus in order to get to a specific element in the sequence one has to iterate through the list which takes linear time. Apart from that it also takes up a bit more extra space when compared to vectors, which it uses to keep track of the links to previous and next elements corresponding to each element in the sequence.
Getting started with STL in C++. The Standard Template Library (STL) in C++ is nothing but a set of template classes which provides us with the widely used data structures such as lists, stacks, maps, etc. along with iterators, functions and algorithms in order to play around with the data elements.
In this lesson we study about list container and different functions of list. List | C++ STL (Standard Template Library) | std::list.
In this article, we will be focusing List in C++ in detail. Standard Template Library is a generic library that comprises of different c++ template classes. It includes various classes and methods that can operate on different types of data records/values. By this, we mean that, we need not define classes and methods over and over to perform the same operation on different data type values.
C++ List is the inbuilt sequence containers that allow non-contiguous memory allocation. Functions used with List in C++ are push_back() and front_back().
