🚀 Pointers and Arrays in C++ Arrays in C++ are contiguous blocks of memory, and the array name often decays into a pointer to the first element of the array. Pointer arithmetic can be used to traverse an array. Adding an integer to a pointer increments the pointer's address by that integer times the size of the data type it points to. This makes pointers and arrays closely related in C++. 💪 Stop scrolling.

🔥 Day 12 of 100 Days of Code — Inversion Count Problem (C++) Today I worked on a classic and very important problem in DSA: Inversion Count. An inversion occurs when a pair of indices (i, j) satisfies: 👉 i < j 👉 arr[i] > arr[j] This problem is especially useful in understanding how efficient sorting algorithms (like Merge Sort) work internally. 🧠 Key Learning: Instead of checking every pair (which takes O(n²)), we can use a modified Merge Sort approach to count inversions in O(n log n) time. This makes the algorithm scalable even for large input sizes! 💻 Here’s the approach in C++: #100DaysOfCode #DSA #C++ #CodingJourney #Programming #LearningEveryday

Ever wondered how your favorite apps and games are made? It all starts with programming! 💻 Programming is essentially giving instructions to a computer in a language it understands. It's like writing a recipe, but for a machine to follow. Mastering a programming language opens up a world of possibilities, letting you create anything from simple scripts to complex AI. #Programming #Coding #LearnToCode #CSE #Hello_World #OmniCodeLab #CodingForBeginners #SoftwareDevelopment

Pass-by-Value vs Pass-by-Reference Pass-by-Value: When a variable is passed to a function, a copy of the value is made. Any changes inside the function don’t affect the original variable. Pass-by-Reference: Here, instead of a copy, a reference (or address) to the original variable is passed. So, any change made inside the function directly affects the original variable. For simple term : Pass-by-Value = “I made a copy for you.” Pass-by-Reference = “You’re using the original one.” #Programming #CodingConcepts #SoftwareDevelopment #Learning #ComputerScience

🚀 Algorithm Challenge #11 🧠 Problem Title: Calculate the average of three marks and determine whether the student passes or fails based on the average. ✅ Language Used: C++ 💡 What it covers: Taking multiple inputs from the user Performing arithmetic calculations (average) Using if-else statements for decision making Basic output formatting 📂 GitHub Repo: 🔗 https://lnkd.in/dQ-E5FJj 📝 Short Description: In this challenge, I wrote a simple C++ program that asks the user to enter three exam marks. The program calculates their average and displays whether the student passes or fails depending on whether the average is 50 or higher. It’s a practical example of applying basic input/output and conditional logic — one of the core skills for programming beginners. 💬 Feedback Welcome!

📅 Day 35 of #100DaysOfCode Problem: Search in Rotated Sorted Array II (LeetCode 81) Approach: 1️⃣ First, handled duplicates by skipping consecutive equal elements from both ends to avoid confusion while finding the rotation point. 2️⃣ Used a modified binary search to find the pivot (the smallest element’s index) — this separates the rotated parts of the array. 3️⃣ Performed binary search on both halves — before and after the pivot — to check where the target lies. 4️⃣ Returned true if found in either part, else false. #100DaysOfCode #LeetCode #BinarySearch #RotatedArray #ProblemSolving #Algorithms #DSA #Cplusplus #CodingChallenge #Programming #DeveloperLife #CodeNewbie #DailyDSA #TechCommunity #KeepLearning #SoftwareEngineering #LearningInPublic #Motivation

🚀 String Views in C++17 and Beyond C++17 introduced `std::string_view`, a non-owning reference to a contiguous sequence of characters. `std::string_view` provides a way to access string data without copying it, improving performance and reducing memory usage. It can be used with both `std::string` objects and C-style strings. `string_view` objects are lightweight and efficient for read-only access to string data. They avoid unnecessary allocations and copies. 📖 Learn one new thing daily — become 1% better every day! 🚀 Accelerate your tech journey — 10k+ bite-sized concepts, 4k+ deep-dive articles, 12k+ quizzes! 📱 Get the app: https://lnkd.in/gefySfsc 🌐 Visit us: https://techielearn.in #c++ #programming #coding #tech #learning #professional #career #development
