all usefull stls in cpp imports

The C++ Standard Library provides a set of useful Standard Template Libraries (STLs) that can be imported into your C++ programs. These libraries offer a wide range of data structures and algorithms that can greatly simplify the programming process. Here are some of the most commonly used STLs in C++, along with explanations for each:

  1. : This library provides input/output functionality in C++. It includes classes such as std::cin and std::cout for reading and writing data from/to the standard input/output streams.

  2. : The vector library provides a dynamic array-like container that can store objects of any type. It offers functions to add, remove, and access elements in a vector, and automatically manages the memory allocation.

  3. : The string library provides a set of functions and classes for working with strings in C++. It includes functions to manipulate strings, such as concatenation, comparison, and searching.

  4. : This library provides a collection of generic algorithms that can be used to perform operations on containers, such as sorting, searching, and modifying elements. It includes functions like std::sort, std::find, and std::transform.

  5. : The map library provides an associative container that stores key-value pairs. It allows efficient lookup, insertion, and deletion of elements based on their keys. It is implemented as a binary search tree or a hash table, depending on the implementation.

  6. : The set library provides an ordered set of unique elements. It allows efficient insertion, removal, and search operations. It is implemented as a binary search tree or a hash table, depending on the implementation.

  7. : The queue library provides a container adapter that allows elements to be inserted at one end and removed from the other end. It follows the First-In-First-Out (FIFO) principle.

  8. : The stack library provides a container adapter that allows elements to be inserted and removed only from one end. It follows the Last-In-First-Out (LIFO) principle.

  9. : The list library provides a doubly linked list container that allows efficient insertion and removal of elements at any position. It does not support random access like vectors or arrays.

  10. : The deque library provides a double-ended queue container that allows efficient insertion and removal of elements from both ends. It supports random access like vectors, but also allows efficient insertions and deletions at both ends.

These are just a few of the many useful STLs available in C++. Each library provides a set of functions, classes, and data structures that can greatly simplify your programming tasks. By including the appropriate headers and importing these libraries, you can leverage their functionalities to write more efficient and concise code.
