Introduction A stack is a linear data structure in C++ that follows the LIFO (Last In, First Out) principle, it means the element that is inserted last is the first one to be removed. Stacks are commonly used in programming for tasks such as function calls, expression evaluation, undo/redo operations, and backtracking. It can be implemented using arrays, linked lists, or by using the built-in stack container from the Standard Template Library (STL). Understanding stacks helps beginners learn how data is managed and accessed in a structured and efficient way. Let’s Explore Stack Data Structure in C++ Today, we are going to use Stacks in C++ . We can make using either by using arrays or linked lists . A stack in C++ is a data structure that follows the Last In, First Out (LIFO) rule. This means the last element added is the first one removed, like a stack of books. In C++, stacks are commonly used through the STL std::stack . You can add elements using push() , remove the top eleme...

 If you’ve already learned HTML , you know how to create the structure of a webpage — headings, paragraphs, images, and links. But without styling, an HTML page looks plain and boring. This is where CSS comes in. In this blog, you’ll learn what CSS is, why it’s important, and how it works together with HTML to create beautiful and modern websites. What Is CSS? CSS stands for Cascading Style Sheets . CSS is used to style and design webpages . It controls how HTML elements look on the screen, such as: Colors Fonts Spacing Layout Animations In short: HTML gives structure, CSS gives style. Role of HTML vs CSS Think of a webpage like a house: HTML = walls, rooms, doors (structure) CSS = paint, furniture, decorations (appearance) Both are essential to build a complete website. How CSS Works with HTML CSS works by selecting HTML elements and applying styles to them. For example: Select a heading ( h1 ) Change its color Adjust its si...

 If you’re starting your journey in development, you’ve probably heard people talk about Git and GitHub all the time. They are mentioned in tutorials, job requirements, and open-source projects — but for beginners, they can sound confusing. In this blog, we’ll break things down clearly and simply . By the end, you’ll understand what Git is, what GitHub is, how they are different, and why every developer should learn them . What Is Git? Git is a version control system . That sounds complicated, but here’s what it actually means: Git helps you track changes in your code over time . Imagine you’re working on a project: You change some code Something breaks You want to go back to the previous version Git allows you to do exactly that. What Git Does: Saves different versions of your project Tracks who made what changes Lets you go back to older versions Helps multiple people work on the same project without conflict Git works locally on your compute...

 One of the biggest stories in the social networking world right now is UpScrolled — a new social media app that’s suddenly surged in popularity and climbed the app store charts. In this post, we’ll explain what UpScrolled is, why it’s trending, how it works, and what’s driving people to download it . What Is UpScrolled?

Why UpScrolled Is Trending Now UpScrolled’s popularity has exploded recently — and there are a few key reasons for that: 1. Surg...

Introduction Traversal in a linked list in C++ refers to the process of visiting each node of the list one by one in order to access or display its data. Since linked lists do not store elements in contiguous memory locations like arrays, traversal is done using pointers. Starting from the head node, the program moves through each node by following the link to the next node until it reaches the end of the list. Understanding linked list traversal is essential because it is the foundation for many operations such as searching, updating, inserting, and deleting elements in a linked list. Let’s Explore Linked List Traversal in C++ Today, we are going to learn Traversal in a linked list in C++. Traversal in a linked list refers to the process of visiting each node of the list one after another, starting from the head node and continuing until the last node is reached. During traversal, we can perform operations such as displaying the data, searching for an element, or modifying values. S...

 So far, you’ve learned HTML basics and even created your first simple webpage. But there’s one exciting step left that makes your project feel real — putting your website online so anyone can open it using a link. In this blog, I’ll show you how to host an HTML website online for free , step by step. No payment, no server knowledge, and no advanced tools required. This is perfect for beginners deploying their first real project . What Does “Hosting a Website” Mean?
