Software Engineering Basics of Unordered multiset in C++ An unordered multiset is an unordered set (a set in which a key can be stored in any random order) that allows different elements to have equivalent values (allows duplicate items).
Software Engineering C++ Likely and Unlikely attributes C++ likely and unlikely attributes came into existence with the release of C++ 20. In our C++ code if we know which lines of code would most probably be executed during our code execution then we can use likely and unlikely attributes.
Software Engineering Vector::pop_back() in C++ We have learnt about pop_back() method of Vector class included in std::vector library in C++. Vectors can be considered as dynamic arrays on the basis of its usage.
Software Engineering Create and Delete Folder in C++ This article covers the process of creating and delete a directory (folder) in C++. We have provided the complete C++ implementation.
C++ std::variant in C++ std::variant was added in C++17 to support the sum type. It adds more functionality to union and hence is a safer version of it.
C++ Spaceship operator <=> in C++ The three-way comparison operator , colloquially called the spaceship operator was added in C++20. It is an alternative to basic_string compare() function in C++.
Software Engineering Immediate Functions in C++ Immediate functions or the functions which have consteval keyword before their return type has been introduced with the release of C++ 20 , consteval functions are the functions that must be evaluated at compile time to produce a constant.
Software Engineering Explicit in C++ Explicit is a keyword in C++ which was introduced with C++ 11 this is used to cast a data type and also to change the by default implicit conversion in C++.
Software Engineering Digit Separators in C++ In this article, we have discussed about Digit Separators in C++. This topic is introduced in C++14. Using digit separators in the code make it easy for human readers to parse large numeric values.
Software Engineering Implementing rmdir using C/ C++ We have developed the rmdir command of UNIX systems in C and C++ by using the remove and nftw system functions to delete a directory.
Software Engineering Implementing mkdir in C/ C++ We have developed the mkdir command of UNIX systems in C and C++ by using the mkdir function to create a directory.
Software Engineering Implementing cd command in C/ C++ We have developed the cd command of UNIX systems in C and C++ by using the chdir function.
Software Engineering nullptr (null pointer) in C++ A null pointer (nullptr) is a pointer that does not point to any memory location. nullptr is a keyword that was introduced in C++11 standard to denote a null pointer. This standard also introduced a nullptr_t type.
Software Engineering Different ways to initialize 2D array in C++ We have explored different types to initialize 2D array in C++ like Sized array, Skipping values and Unsized array initialization.
Software Engineering Implementing pwd command in C/C++ We will use the header file dirent.h for directory structures and objects and implement our pwd command in C/C++. This will involve the getcwd() function call.
Software Engineering priority_queue::push() in C++ Push function in priority queue is used to to insert a element in the queue, the element is inserted in the priority queue based on it's value which defines it's priority in the queue.
Software Engineering Different Ways to Initialize Priority queue in C++ We have demonstrated different Ways to Initialize Priority queue in C++ such as using Max Heap, Min Heap and with vector and array.
Software Engineering Arrays vs Vectors in C++ We have explored the differences between array and vectors in C++ in depth along with C++ code examples. Some differences include size of array is fixed while vector is dynamic.
Software Engineering Move Semantics in C++ Move semantics is moving ownership of objects around and this includes concepts of move constructor.
Software Engineering Alternatives to Vector in C++ In this article, we have explored the alternatives of Vector in C++ such as array, Deque, Linked List, map and multiset.
Data Structures Implementing a Binary Search Tree (BST) in C++ In this article, we have explained the idea of implementing Binary Search Tree (BST) from scratch in C++ including all basic operations like insertion, deletion and traversal.
Software Engineering Different ways to add elements in Priority queue in C++ Priority queue is an adapter which uses a vector by default as an underlying container, but a deque can also be used. In this article, we have explored Different ways to add elements in Priority queue container in C++.
Software Engineering unordered_set in C++ STL In this article, we have discussed about the unordered_set container class of the C++ Standard Template Library. unordered_set is one of the most useful containers offered by the STL and provides search, insert, delete in O(1) on average.
Software Engineering Cin and Cout in C++ C++ uses the concept of streams to perform I/O operations. A stream is a sequence of bytes in which character sequences are 'flown into' or 'flow out of'. In this article, we have covered cin and cout in C++ in depth.
Software Engineering Simplified: C++ STL Lists In this article, we have explored List in C++ STL in depth along with its member functions and applications. It is a good alternative to arrays.
