C++ lvalues and rvalues explained

Re-think about C++? Older versions of C++ came from very basic OO paradigm and program components, some from c. They were criticized so much, esp with memory/pointer management. Over years, a lot of new features and fixes are introduced, and C++ gets so 'modern' that a software manager I was talking to a few weeks ago knows barely nothing about pointers but working on C++. With AI assisted coding today, AI can be accurately monitoring and controling all the pointer processing and memory management. Is it time to re-think about lots of C++ changes in recent years? #AIcoding #C++

DSA with C++ | Day 60/120 Dedicated today to revising Hard level String problems solved so far. Revisited key problems like Regular Expression Matching, Wildcard Matching, Longest Valid Parentheses, and Substring with Concatenation of All Words without referring to previous solutions. Focused on strengthening pattern recognition, improving implementation clarity, and deepening understanding of advanced concepts like dynamic programming and string matching techniques. #DSA #Cplusplus #LeetCode #120DaysOfCode #Strings #Revision

C++ Operators: The Real Power Behind Your Code When you start learning C++, variables and data types feel exciting… but the real magic begins when you meet operators. Operators are the tools that make your program think, decide, and act. 💡 🔹 Arithmetic Operators + - * / % These are your basic building blocks. From simple calculations to complex logic—everything starts here. 🔹 Relational Operators == != > < >= <= Want your program to make decisions? These operators help compare values and return true/false. 🔹 Logical Operators && || ! Used when combining multiple conditions. This is where real decision-making begins. 🔹 Assignment Operators = += -= *= /= Not just assigning values—these help you write cleaner and shorter code. 🔹 Increment / Decrement ++ -- Small symbols, big impact. Perfect for loops and counters. Why should you care? Because mastering operators means mastering control over your program. The difference between a beginner and a problem solver often starts here. Pro Tip: Don’t just memorize operators—practice them in real problems. Try combining multiple operators in a single condition and see how your logic improves.

🎯 C++ Level 2: Call Stack Deep Dive Finally understood what happens when functions call functions! 📊 The Stack in Action: main()  → Function1()   → Function2()    → Function3()     → Function4() ← Deepest, prints first     ← returns (POP!)    ← returns   ← returns  ← returns ← main continues 🔧 Key Concepts: • Push: Function called, frame added • Pop : Function returns, frame removed • LIFO: Last In, First Out • Active frame: Top of stack only 💡 Debugging Power: Call Stack window shows entire chain! Click any frame → see its local variables. 🧠 Memory Layout: Each frame contains: - Return address (where to go back) - Parameters - Local variables - Saved registers ⚠️ Stack Overflow: Too many nested calls = crash Infinite recursion = stack explosion Code: https://lnkd.in/d9N7FYWe #cpp #programming #callstack #memory #debugging #learninginpublic #lowlevel

Day 4: My first real C++ project Image suggestion: I built a command-line arithmetic calculator in C++ that takes two numbers from the user and returns the sum, difference, product, and quotient. Simple? Yes. But it taught me: - Modular programming with header files - Integer vs double division (there's a difference) - How to structure a real project Link in comments. What was your first project? #CPlusPlus #Projects #LearningToCode

Mutex might sound like the solution here, but you also essentially lose the parallelism by making the thread wait for other threads to finish work. Things LIKE atomics should be considered the defacto answer, mutexes are a last resort.

🔄 C++ Level 2: Mastered Recursion! From "function calls itself??" to "elegant problem solver" 🎯 The Two Rules: 1. Base case: STOP condition (Power == 0) 2. Recursive case: smaller problem (Power - 1) 🔢 MyPower(2, 3) trace: MyPower(2,3) → 2 * MyPower(2,2) → 2 * (2 * MyPower(2,1)) → 2 * (2 * (2 * MyPower(2,0))) → 2 * (2 * (2 * 1)) ← Base case! → 8 📊 Call Stack in Action: Each call adds frame → stack grows Base case reached → stack unwinds Returns propagate back up ⚠️ Stack Overflow Lesson: MyPower(2, 99992) → 💥 Crash! Stack limit ~10,000-50,000 frames Solution: Fast exponentiation (O(log n)) 💡 Homework Completed: ✓ Print N to M (ascending) ✓ Print M to N (descending)   ✓ Power function (Base^Power) Code: https://lnkd.in/d9N7FYWe #cpp #programming #recursion #callstack #algorithms #learninginpublic

🚀 Day 4 of mastering C++ Today was all about exploring the power of STL containers — the real game-changers in writing efficient code. From dynamic arrays with vectors to pairing data effortlessly using pairs… and exploring containers like arrays, lists, stacks, queues, deques, sets, maps, and unordered variants — it’s amazing how much complexity can be simplified with the right tools. 💡 What I realized: Good programmers don’t just write code — they choose the right containers to make code smarter, faster, and cleaner. Still a long way to go, but enjoying every bit of this journey. #C++ #STL #LearningInPublic #CodeNewbie #DataStructures

Following up on my previous post… One thing I’ve started paying more attention to while learning C++: 👉 Not just how a feature works 👉 But when it became relevant Some simple but important shifts: - C++11: Workarounds like deleting/private copy constructors were common - C++17: Guaranteed copy elision changed how we think about returns - Modern C++: Cleaner code is often already optimal The takeaway: Writing good C++ today means being aware of the version context. Same code. Same intention. Different standard → different implications.

#Day-3 of 30 Days/30 Posts challenge. 👉 upgrading the C++ advanced concepts.... Pointers and References in C++—two concepts that look similar at first, but completely change how you think about memory. When I started learning C++, I used them without truly understanding the difference. But once I did, it changed how I write and reason about code. 🔹 What is a Pointer? A pointer is a variable that stores the address of another variable. 👉 You can: Reassign it Make it point to different variables Even have a null pointer int a = 10; int* p = &a; 🔹 What is a Reference? A reference is an alias (another name) for an existing variable. 👉 You cannot: Reassign it Make it null Change what it refers to int a = 10; int& r = a; ⚔️ Pointers vs References Feature Pointer Reference Can be null ✅ Yes ❌ No Can be reassigned ✅ Yes ❌ No Requires dereferencing ✅ Yes (*p)❌ No Safer to use ❌ Less safe ✅ More safe Memory address access ✅ Direct ❌ Indirect 💡 When to use what? 👉 Use Pointers when: You need flexibility (dynamic memory, data structures) You may not have a value initially (null) 👉 Use References when: You want safer, cleaner code You are passing variables to functions 🧠 My Key Learning Understanding pointers and references is not just syntax—it’s about: 👉 Ownership 👉 Memory control 👉 Writing efficient and safe code Once this clicked, C++ stopped feeling complex and started making sense. Still learning, one concept at a time 🚀 #CPP #Pointers #References #ModernCPP #Programming #SoftwareEngineering #LearningJourney
