c stl containers
Many containers have several member functions in common, and share functionalities. The decision of which type of container to use for a specific need does not generally depend only on the functionality offered by the container, but also on the efficiency of some of its members (complexity).
Updated: 20191017 Previously we’ve looked at the C++ array and vector containers and saw why those containers are better than standard C-style arrays. We also learned that containers can take advantage of idioms such as the SBRM design pattern and range-based for loops. Now that we’ve looked at two containers in depth (as well as Continue reading “An Overview of C++ STL Containers”
The Standard Template Library (STL) is a software library for the C++ programming language that influenced many parts of the C++ Standard Library. It provides four components called algorithms, containers, functions, and iterators. The STL provides a set of common classes for C++, such as containers and associative arrays, that can be used

Der Erste ist der Datentyp der Array-Elemente, der Zweite ist die Anzahl der Array-Elemente. Ein std:: array ist im Grunde nichts anderes, als ein gewöhnliches C-Array, mit den zusätzlichen Eigenschaften eines STL-Containers.
This example is based on the idea of the STL containers and iterators. A container is an object that represents a group of elements of a certain type, stored in a way that depends on the type of container (i.e., array, linked list, etc.). An iterator is a pointer

STL containers are not only generic in terms of type of elements but also in terms of functionality. There are lot of functionality and members are common across the containers. Here are major examples: All sequence containers support uniform initialization and
Containers Library in STL gives us the Containers, which in simplest words, can be described as the objects used to contain data or rather collection of object. Containers help us to implement and replicate simple and complex data structures very easily like arrays, list, trees, associative arrays and many more.
Associative containers The STL standard associative containers (set, multiset, map, multimap) allow access to elements using a key: For set and multiset element is its own key. For map and multimap elements are of type pair. pair is a standard
The Standard Template Library’s list container is implemented as a doubly linked list.You might wonder why there are both list and vector containers in the STL — the reason is that the underlying representations are different, and each representation has its own costs
These collections may be containers or subsets of containers. We will discuss about all the three C++ STL components in next chapter while discussing C++ Standard Library. For now, keep in mind that all the three components have a rich set of pre-defined functions which help us in doing complicated tasks in very easy fashion.
C++ offers three types of containers. These containers are known as Sequential, Associative and Unordered. Learn what makes them different and how you can use them in your app. I have to confess, I have grown tired of using the same container type in my game
