The multimap in the C++ Standard Template Library (STL) is an associative container similar to map, but it allows multiple values for the same key. It is useful in cases …

The map container in the C++ Standard Template Library (STL) is an associative container that stores key-value pairs, where each key is unique. The elements in a map are automatically …

The list container in the C++ Standard Template Library (STL) is a doubly linked list. Unlike arrays or vectors, list allows fast insertion and deletion at both ends, as well …

The forward_list in the C++ Standard Template Library (STL) is a single-linked list container. Unlike list, it only allows traversal in one direction (forward), making it more memory-efficient but less …

The bitset in the C++ Standard Template Library (STL) is a container that represents a fixed-size sequence of bits (binary values) as 0s and 1s. It provides an efficient way …

The deque (double-ended queue) in the C++ Standard Template Library (STL) is a sequence container that supports fast insertion and deletion at both the front and back. It’s similar to …

The C++ Standard Template Library (STL) Containers provide a variety of data structures to store and manage data. STL containers are divided into three main types: Sequence Containers: Store data …

The C++ Standard Template Library (STL) Algorithms provides a powerful suite of functions for working with data in containers like vector, deque, list, and array. These algorithms cover common tasks …

The C++ Standard Template Library (STL) is a powerful library that provides a variety of container classes, algorithms, and iterators to make programming more efficient and organized. It includes several …

In C++, cerr is an object of the ostream class used to output error messages to the standard error stream. The cerr stream is typically unbuffered, meaning that messages are …

In C++, cout is an object of the ostream class and is used to output data to the standard output device, typically the console. The cout object is part of …

In C++, cin is an object of the istream class and is used to take input from the standard input device, typically the keyboard. The cin object reads input from …
