When using std::getline after a formatted extraction (like std::cin >>), you might see an unexpected behavior, where std::getline is skipping the next input line. In this article, we will understand why this happens and how to handle it. Getline skipping input after formatted extraction The code below shows how getline() is skipping input after a formatted extraction: #include #include using namespace std; int main() { string name; string city; cin

Binary Search Tree (BST) is a special binary tree in which the left subtree of a node contains only nodes with values less than the node's value, and the right subtree contains only nodes with values greater than the node's value. In this article, we will learn how to perform a right rotation on a BST node using C++. What is Right Rotation in BST? Right rotation is a type of tree rotation technique that is used to balance a binary search tree. In the right rotation around a node, the node is moved to the right in such ... Read More

Binary Tree traversal is a process of visiting all the nodes in a certain order. In this article, we will learn how to perform postorder non-recursive traversal of a binary tree using two stacks in C++. What is Postorder Non-Recursive Traversal? Postorder traversal is a type of depth-first traversal where we first visit the left subtree, then the right subtree, and then the root node. In a non-recursive approach, we are not allowed to use recursive functions to track nodes for traversing the tree. Instead, we can use stack data structures to manually keep track of the nodes. This ... Read More

A Binary Search Tree (BST) is a sorted binary tree in which each node follows two key properties: The right subtree of a node contains only keys greater than the node's key. The left subtree of a node contains only keys less than the node's key. Additionally, each node has at most two children. Tree Rotation Tree rotation is an operation that changes the structure without interfering with the order of the elements on a binary tree. It moves one node up in the tree and one node down. ...

Binary Tree traversal is a process of visiting all the nodes in a certain order. In this article, we will learn how to perform inorder non-recursive traversal of a binary tree using a stack in C++. What is Inorder Non-Recursive Traversal? Inorder traversal is a type of tree traversal, where we first visit the left subtree, then the root node, and then the right subtree. In a non-recursive approach, we are not allowed to use recursive functions to track nodes for traversing the tree. Instead, we can use an explicit stack data structure to track nodes and traverse through ... Read More

A dictionary is a collection of key-value pairs where, keys are unique and used to identify corresponding values in the dictionary. In this article, we will learn how to perform dictionary operations such as insertion, search, and traversal using a binary search tree (BST) in C++. What is BST? A binary search tree (BST) is a tree data structure, where each node has at most two children and follows two rules: the left subtree contains keys less than the node’s key, and the right subtree contains keys greater than the node’s key. This structure is same as how a ... Read More

A ternary tree is a type of tree data structure in which each node can have at most three children. In this article, we will learn how to implement a ternary tree in C++ using basic class structures and pointers. What is Ternary Tree? A ternary tree is a tree in which each node has up to three children, that is left, middle, and right. It is same as a binary tree, but with an extra child node for each node. Each node in a ternary tree stores a data value and pointers to its three child nodes. ... Read More

In this section, we will see how to convert an integer to a string.The logic is very simple. Here we will use the sprintf() function. This function is used to print some value or line into a string, but not in the console. This is the only difference between printf() and sprintf(). Here the first argument is the string buffer. where we want to save our data.Input: User will put some numeric value say 42 Output: This program will return the string equivalent result of that number like “42”AlgorithmStep 1: Take a number from the user Step 2: Create an ...

Tokenization refer to the process of breaking a string based on certain delimiters such as spaces, commas, semicolons, or any other character. Mostly white spaces are used as delimiters to tokenize strings. In this article, we will discuss all the ways tokenize a string in C++. For example, if we have a string like "Hello, World! Welcome to Tutorialspoint.", we can tokenize it like this: string str = "Hello, World! Welcome to Tutorialspoint."; tokens = {"Hello", "World", "Welcome", "to", "Tutorialspoint"}; Tokenizing a String in C++ In C++, we can tokenize a string using various methods. Here are ... Read More

There is no one elegant way to iterate the words of a C/C++ string. The most readable way could be termed as the most elegant for some while the most performant for others. I've listed 2 methods that you can use to achieve this. First way is using a stringstream to read words separated by spaces. This is a little limited but does the task fairly well if you provide the proper checks. For example, >Example Code Live Demo#include #include #include #include using namespace std; int main() {    string str("Hello from the dark side");   ... Read More
