Safe mutex lock: std::lock_guard = automatic unlock when scope ends. #CppTips #Multithreading #ModernCpp
Catch compile-time errors! static_assert = sanity check during compilation. #Cpp17 #CppTips #BestPractices
Sum easily! std::accumulate = cleaner than loops. #CppTips #STL #CodingHacks
noexcept functions = tell the compiler no exceptions, better optimization. #CppTips #ModernCpp #Performance
We often hear “reduce your memory footprint”. But what exactly is it, and why should we even care? Let’s decode it step by step 👇 #CppTips #Coding #LowLevelDesign #Cpp #cpptutorials #cppprogramming
Memory & cache behavior: unordered_map → higher memory footprint (due to buckets). map → pointer-heavy but cache-friendly for small datasets. Small data + ordered iteration → map. Large random access data → unordered_map.
Efficient binary storage: std::bitset = fixed-size binary representation made simple. #CppTips #Optimization #Cpp17
Regex made easy! std::regex = powerful string pattern matching. #CppTips #STL #ModernCpp
Cleaner type inference: auto + decltype = safer & less verbose code. #CppTips #Cpp17 #CodingHacks
Delete vs private functions! Use delete keyword to disable unwanted functions safely. #CppTips #ModernCpp #BestPractices
💡 C++ Hack: Don’t mix normal output & errors! cout → regular output cerr → error messages, prints instantly cerr << "Oops! Invalid input!" << endl; Pro tip: Use cerr for bugs & warnings, not results. #CppTips #Coding
Modern file handling: std::filesystem (C++17) = easier & safer file operations. #Cpp17 #CppTips #STL
Optimize branches! [[likely]] / [[unlikely]] hints the compiler for faster execution. #CppTips #ModernCpp #Performance
Rule of 5 = memory safety! Define copy/move constructor & assignment operator properly. #CppTips #Cpp17 #MemoryManagement
Lock mutex safely! std::scoped_lock = automatic mutex management without manual unlock. #CppTips #Multithreading #Cpp17
Safer byte handling! std::byte > raw char buffers for memory safety. #CppTips #ModernCpp #CodeSafety
Hold any type safely! std::any stores any type, but type-check before use. #CppTips #STL #Programming
Avoid unused warnings! [[maybe_unused]] keeps your experimental code clean. #CppTips #ModernCpp #BestPractices
#cpp Functional loops! std::for_each with lambdas = cleaner than traditional loops. #CppTips #STL #CodingHacks
#cpp Structured bindings = cleaner code! Unpack tuples/pairs elegantly. #CppTips #Cpp17 #CodeClean
#cpp Safe multithreading! std::thread + RAII = safer concurrency. #CppTips #Multithreading #ModernCpp
