The C++ Standard Library provides a comprehensive set of classes and functions that are widely used in C++ programming. It includes input/output streams, containers, algorithms, and more. This reference guide will help you understand the various components of the C++ Standard Library.

Containers

The C++ Standard Library includes several container classes that are used to store and manipulate collections of data. Here are some of the most commonly used containers:

  • Vector: A dynamic array that can grow and shrink in size.
  • List: A doubly-linked list that allows for efficient insertion and deletion of elements.
  • Queue: A first-in, first-out (FIFO) collection.
  • Stack: A last-in, first-out (LIFO) collection.

Algorithms

The C++ Standard Library provides a wide range of algorithms that can be used to perform operations on collections of data. These algorithms are designed to be efficient and easy to use.

  • Sort: Sorts the elements of a container in ascending or descending order.
  • Search: Searches for an element in a container.
  • Transform: Copies elements from one container to another, applying a specified operation to each element.

Input/Output Streams

The C++ Standard Library provides input/output streams for reading from and writing to files, standard input/output, and other devices.

  • iostream: Provides input/output operations for standard input/output.
  • fstream: Provides input/output operations for files.
  • sstream: Provides input/output operations for strings.
