C++ is a programming language that provides a wide variety of data structures. Here are some of the most commonly used data structures in C++:
- Arrays - a collection of elements of the same data type that are stored in contiguous memory locations.
- Vectors - a dynamic array that can grow or shrink in size as needed.
- Linked lists - a collection of nodes that contain data and a pointer to the next node in the list.
- Stacks - a collection of elements that follows the last-in-first-out (LIFO) principle, meaning the last element added is the first one to be removed.
- Queues - a collection of elements that follows the first-in-first-out (FIFO) principle, meaning the first element added is the first one to be removed.
- Trees - a hierarchical data structure that consists of nodes connected by edges.
- Graphs - a collection of nodes (vertices) connected by edges, which can be directed or undirected.
- Hash tables - a data structure that uses a hash function to map keys to values in an array, allowing for constant-time insertion, deletion, and retrieval of data.
- Heaps - a binary tree-based data structure that follows the heap property, which means that the parent node is either greater or smaller tha
