C++ nth_element in C++ STL nth_element is a function in the C++ Standard Template Library (STL) that allows you to partially sort a range of elements in a container, such that the element at the nth position is the one that would be at that position if the entire range was sorted.
C++ Queue::emplace in C++ STL In this article at OpenGenus.org, we will discuss emplace method of Queue container in C++ STL.
Algorithms Modular Multiplication in C++ Modular arithmetic is a branch of number theory that deals with operations on numbers that have a remainder when divided by a modulus. In C++, performing modular arithmetic involves using the % (modulo) operator and sometimes ensuring that the result remains within a specified range.
C++ Different Ways to Delete Elements in Unordered Map in C++ STL In this OpenGenus article, we will look at the various ways of deleting elements in an unordered map in C++.
C++ Vector of array in C++ The vector of arrays in C++ is an excellent tool for efficiently managing fixed-size arrays within a vector. This approach is particularly advantageous for organizing grouped data where each array shares a uniform size.
C++ How to Use Friend Classes in C++ to Access Private and Protected Members In this article at OpenGenus, we will be going over friend classes in C++, what they're used for, usage examples, difference between friendship and inheritance, and alternatives.
C++ Lazy initialization in C++ Lazy initialization is a technique where the creation of an object is deferred until it is actually needed. This can improve performance by avoiding the creation of objects that are never used.
C++ Bank Management System in C++ [Project with source code] In this article at OpenGenus, we will cover how to create a bank management system in C++ programming language. A bank management system can be used to manage a bank account, withdraw and deposit funds, and check the account balance.
Software Engineering Adapter Design Pattern In this article at OpenGenus, we show two ways to implement the Adapter design pattern.
C++ 50 Interview questions on C++ Struct In this article at OpenGenus, we have presented 50 interview questions based on struct (Structure) in C++ and C Programming Language. Each question is provided with the answer and detailed explanation.
C++ Min / Max Heap in C++ using STL In this article at OpenGenus, we are going to study and explore Min / Max Heap in C++ using STL. We will see their definition, usage and how we are going to apply them to solve various complex problems in C++ language.
C++ Floyd Warshall Algorithm in C++ Floyd Warshall Algorithm is one of the famous graph algorithm for finding shortest path between a node to every other node. In this article at OpenGenus, we have implemented Floyd Warshall Algorithm in C++ programming language.
C++ Spell Checker Console Application in C++ [Project] In this article at OpenGenus, we will cover how to create a spell checker application using C++ programming language.
C++ Heap in C++ using OOP and Template In this article at OpenGenus, we will explore how to implement the heap data structure in C++ using principles of object-oriented programming (OOP) and templates.
C++ Multilevel inheritance in C++ Multilevel inheritance is a form of inheritance where a base or child class has multiple parent classes and can be extended to any level.
C++ Hash Map in C++ using OOP and Template In this article at OpenGenus, we will review the fundamental concepts of a hash map, how to implement them in C++ using OOP concepts and Template, and useful applications.
C++ Hangman Game in C++ In this article at OpenGenus, we will cover how to create a console hangman game in C++ programming language. Hangman is a popular word-guessing game that involves one player picking a random word, providing the number of letters in that word.
C++ Map::swap() in C++ The swap() function in C++ is used to interchange the elements of two variables. Similarly, the Map::swap() member function is used to swap the elements of two map objects.
C++ Selection Sort in C++ using Inheritance and Template - Recursive and Iterative In this article at OpenGenus, we will explore how to implement Selection Sort in C++ using the principles of object-oriented programming (OOP) and templates. We will define both recursive and iterative approaches to the algorithm.
C++ Doubly Linked List in C++ using OOP and Template In this article at OpenGenus, we will review how we can utilize OOP and templates to create a versatile and efficient implementation of a doubly linked list in C++.
C++ Insert element in unordered_map in C++ STL [3 methods] In this article at OpenGenus, we will explore different ways to insert elements in unordered_map in C++ STL. This can be greatly helpful in using maps and solving complex coding questions.
C++ Map of Sets in C++ STL In the C++ STL (Standard Library), the means to use a variety of containers are provided to arrange efficient methods of managing and manipulating data. In this article, we have explored Map of Sets.
C++ Vector of Map in C++ In this article at OpenGenus, we will mainly know about vector of map. Beforehand, we will know briefly about what is vector in C++. Vector is a part of Standard Template Library of C++.
C++ Stack::Empty in C++ STL Among the available functions provided by the C++ standard library is the stack::empty function. Stack::empty is used to determine whether a given stack is empty. The function returns true if the stack is empty and false if it is not empty.
