C++Now 2025: David Sankel on Program Correctness and Limitations

Delving into advanced C++ unlocks powerful features like smart pointers for safer memory management, template metaprogramming for flexible code, lambda expressions for concise inline functions, and multithreading for parallel computing. Mastering these topics not only improves code efficiency and reliability but also equips you to tackle complex system-level programming challenges. Whether you’re building high-performance applications, real-time systems, or scalable software, understanding advanced C++ concepts is your key to writing modern, robust, and maintainable code. Let’s explore the landscape of modern C++ together and push the boundaries of what this language can achieve!"

Examining the enduring relevance of C programming in the face of newer languages like Zig. This project explores C's strengths: its established toolchain, broad portability, and continued evolution with the C23 standard. Discover how C's explicit memory management and minimal syntax provide clarity and control, essential for systems programming. Use cases in embedded systems and high-performance computing highlight C's practical advantages. Explore the details here: https://lnkd.in/gmrZsVV8 #Cprogramming #SystemsProgramming #EmbeddedSystems

The right way to learn C is to understand how it translates to assembly/machine code and what the CPU will do as a result. Presenting - "C Language (Using RISC-V ISA)" This course dives into the practical applications of the C language, emphasizing hands-on learning to solidify key concepts. Delivered in an engaging and unconventional style, the lessons go beyond theory, equipping you with the skills to apply C programming in real-world scenarios. By the end of the course, you’ll feel confident in your mastery of the C language, adept at using it alongside the tools and utilities professional C programmers rely on daily.

Book recommendation for my network! "C++ in Embedded Systems: A practical transition from C to modern C++" by Amar Mahmutbegović is an absolute gem. This is the definitive guide I wish I had years ago. It masterfully bridges the gap between traditional C and the power of modern C++ for embedded development. It gives you the confidence to use C++ by focusing on: - Zero-cost abstractions - Safe resource management (RAII) - Type-safe programming - Compile-time computation It's a practical book for writing firmware that is safer, more maintainable, and just as efficient. Highly recommended! Thank you Amar Mahmutbegović Sir. #EmbeddedSystems #Cpp #ModernCpp #Firmware #Cprogramming #BookRecommendation #Tech

Lessons from 4 weeks of exploring predictable, high-performance C++. Here’s my 4-week recap — summarizing the core ideas, concepts, and design considerations that shaped my understanding of low-latency systems.

🚀 Create Two-Dimensional Arrays in Modern C++ Using Alias Templates In modern C++, we prefer using std::array over raw C-style arrays. Creating a one-dimensional array is clean and straightforward: std::array arr { 1, 2, 3, 4, 5 }; // CTAD (C++17) But things get verbose when creating a two-dimensional array: std::array<std::array<int, 4>, 3> arr {{ { 1, 2, 3, 4 }, { 5, 6, 7, 8 }, { 9, 10, 11, 12 } }}; 👉 Notice the double braces. This happens because std::array is essentially a struct containing a single C-style array member, so we need an extra level of braces to initialize it. The syntax is correct — but it's not elegant. It’s verbose, easy to misread, and the template arguments (Col, Row) are reversed from how we naturally think about matrices. 💡 Alias templates to the rescue. We can simplify the syntax using an alias template: template <typename T, std::size_t Row, std::size_t Col> using Array2d = std::array<std::array<T, Col>, Row>; Now creating a 2D array becomes clean and intuitive: Array2d<int, 3, 4> arr {{ { 1, 2, 3, 4 }, { 5, 6, 7, 8 }, { 9, 10, 11, 12 } }}; ✔️ More concise ✔️ Less error-prone ✔️ Easier to read and maintain Alias templates are a powerful part of modern C++, and small improvements like this can significantly clean up code in real projects. 📘 Reference: LearnCpp.com — Multidimensional std::array

#C++ #Template_Programming #Embedded_Software_Development In this code snippet i have implmented CAN data frame by using C++ template type available in Standard template library so i am not using macros. C++ templates are very powerful offering compile time checking unlike macros not offering compile time checking and very hard to diagnose but still used today so we can use specific subset of C++ features for embedded software development if classes and objects can create a bloated and hard to analyze code . I will be sharing more information about C++ Standard template library and how C++ can be used in embedded software development effciently. If someone wants to learn more about CAN then have a look here : https://lnkd.in/dZDBDMw8

Another head-spinning course. I think for Rust devs, C++ is very helpful because Rust devs might need to translate a lot of C++ stuff to Rust in the future. Not just OOP, STL, or the basics ... it’s essential to dive into modern C++ concurrency and the deep system-level techniques used in Drivers and Kernel development. C++ shines with its unmatched control and performance tuning capabilities, while Rust brings safety and elegance to systems programming. Together, they form a powerful combination for anyone serious about mastering low-level programming craftsmanship. Learning both rewires the way you think about performance, memory, and parallelism. https://lnkd.in/gaZ-b_Ew #Rust #Rustc #Cpp #C++ #SystemEngineering #Concurrency #ModernCpp #EmbeddedProgramming #Drivers #LowLevelProgramming #SystemsProgramming #Performance #MemoryManagement #SafeSystems

Hello everyone! 🚀 Excited to share my new C++20 library: frtclap! frtclap is a header-only, reflection-inspired CLI parser for C++20, designed to let you define command-line arguments as plain structs - with automatic flag mapping, type-safe parsing and support for subcommands. Key Features: - Header-only -- no build, no linking, no external dependencies - Automatic flag mapping ("input" -> "--input") - Customizable names with frtclap::rename - Subcommands using std::variant and std::visit - Type-safe parsing for strings, integers, vectors and more ⚠️Important: frtclap is still experimental. Many features are yet to be implemented -- like automatic help messages, short flags, nested subcommands. 💡 I’m actively looking for contributors! If you’re interested in modern C++ design, compile-time reflection, and building a clean CLI parser, your help would be hugely appreciated. Check it out on GitHub: https://lnkd.in/dM8GZMmG #Cplusplus #CPP20 #OpenSource #CLITools #HeaderOnly #BoostPFR #Reflection #Programming #ContributorsWanted A snippet of example usage is below:

Reflection in modern C++ enables code, which maps command line arguments directly to a struct. It turns handling CLI parameters to an easy task . Thanks Fırat Özkan for the library Has anyone else nice examples with C++ reflection?
