Stl Cheat Sheet

An STL cheat sheet is a quick reference guide or summary that provides information and examples for using the STL (Standard Template Library) in programming languages such as C++ to work with data structures and algorithms. It helps developers understand and use the various functions, classes, and templates within the STL effectively.

FAQ

Q: What is STL?A: STL stands for Standard Template Library.

Q: What is the purpose of STL?A: The purpose of STL is to provide a set of reusable algorithms and data structures in C++.

Q: What are some commonly used containers in STL?A: Some commonly used containers in STL are vectors, lists, queues, and maps.

Q: What are iterators in STL?A: Iterators in STL are used to iterate over the elements of a container.

Q: What is an algorithm in STL?A: In STL, algorithms are functions that operate on sequences of elements.

Q: What are some examples of algorithms in STL?A: Some examples of algorithms in STL are sort, find, and transform.

Q: What is the difference between vector and list in STL?A: Vectors provide fast random access while lists provide efficient insertion and deletion at any position.

Q: What is the difference between stack and queue in STL?A: Stack is a last-in, first-out (LIFO) data structure while queue is a first-in, first-out (FIFO) data structure.

Q: What is the difference between map and unordered_map in STL?A: Map is an ordered key-value container while unordered_map is a hash-based key-value container.

Q: What is the header file for STL in C++?A: The header file for STL in C++ is <iostream>.
