Tip of the day
Focus on mastering pointers and memory management early. These are core to C programming and often the source of bugs. Use tools like valgrind to catch memory leaks and undefined behavior—it’ll save you time and improve the quality of your assignments.
News
May 2025, the Lightweight Communication Interface (LCI) was released, offering a fast, low-overhead C/C++ library for efficient asynchronous multithreaded communication—ideal for assignments involving parallel computing.
