C++17: What is std::string_view and how to use it?

🚀 Recursion in C++ Functions Recursion is a programming technique where a function calls itself to solve a smaller instance of the same problem. A recursive function must have a base case that stops the recursion, preventing infinite loops. Recursion is often used for problems that can be naturally broken down into smaller, self-similar subproblems, such as traversing tree structures or calculating factorials. While elegant, recursive solutions can sometimes be less efficient than iterative solutions due to function call overhead.

🚀 Introduction to Classes and Objects in C++ Classes are blueprints for creating objects. An object is an instance of a class. Classes encapsulate data (member variables) and functions (member functions) that operate on that data. This is the foundation of object-oriented programming in C++. Classes promote code reusability, modularity, and data abstraction. Understanding classes and objects is essential for building complex and well-organized C++ applications. 💡 Learning is the ultimate competitive advantage! 🚀 Accelerate your tech journey — 10k+ bite-sized concepts, 4k+ deep-dive articles, 12k+ quizzes! 🎓 Get started: https://lnkd.in/gefySfsc 🌐 Visit us: https://techielearn.in #c++ #programming #coding #tech #learning #professional #career #development

🚀 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!

🚀 Variadic Templates in C++ Variadic templates allow functions and classes to accept a variable number of template arguments. This is achieved using parameter packs, which can be expanded using recursion or fold expressions. Variadic templates are essential for implementing functions like `printf` or generic tuple classes. They provide a flexible way to handle different numbers and types of arguments in a type-safe manner. Variadic templates significantly enhance the expressiveness of C++ templates. 💪 Stop scrolling.

🚀 Function Pointers in C++ Function pointers are variables that store the address of a function. They allow you to pass functions as arguments to other functions, store functions in data structures, and call functions dynamically. Function pointers are a powerful feature of C++ that enables flexible and dynamic programming. They are often used in callbacks, event handling, and implementing generic algorithms. 🚀 Stay curious.

🚀 Implementing File Copy using C++ streams This example implements file copying using C++ streams. It opens the source file in binary mode for reading and the destination file in binary mode for writing. It reads the source file in chunks of 4096 bytes and writes those chunks to the destination file until the entire source file is copied. Error handling is included to check if either file fails to open. This is a common task in many C++ applications. #c++ #programming #coding #tech #learning #professional #career #development

Day 81/365 : Go basics Q1: How do you convert an integer to a string in Go?  - Use the strconv package import ( "strconv" ) func main() { i := 123 s := strconv.Itoa(i) fmt.Println(s) // "123" } Q2: Can you explain how named return values work in Go? -> Named return values allow you to predefine the return variables in the function signature, simplifying the return statements. func divide(a, b float64) (result float64, err error) { if b == 0 { err = errors.New("division by zero") return } result = a / b return } Q3: How do you use anonymous functions in Go? -- function without a name, often defined inline. func main() { add := func(a, b int) int { return a + b } fmt.Println(add(2, 3)) // Outputs 5 } #GoLang #LearningToCode #Programming #CodingJourney #TechCommunity #GoDevelopers

🚀 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 more on our website: https://techielearns.com #c++ #programming #coding #tech #learning #professional #career #development

🚀 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 33 of #100DaysOfCode Problem: Basic Calculator (LeetCode 224) Approach: 1️⃣ Parsed the string character by character, keeping track of current number, sign, and result. 2️⃣ When encountering '+' or '-', added the previous number to the result and reset the current number. 3️⃣ Used a stack to handle parentheses — pushed the current result and sign when '(' was found, then restored them after ')'. 4️⃣ Carefully computed the final result by adding the last pending number after traversal. #100DaysOfCode #LeetCode #DSA #ProblemSolving #Stack #Cplusplus #CodingChallenge #Algorithms #Math #CodeNewbie #Programming #SoftwareEngineering #CodingJourney #TechCommunity #DeveloperLife #KeepLearning #LearningInPublic #Motivation
