First, C++ can do everything C can do, only better. C is the predominant language for embedded systems, not C++. The latter is mostly suited to 32-bit systems, and 32-bit MCUs still have less than a 40% market share. And a lot of 32-bit systems still run without an OS at all (“bare metal”). Those that do are split between using a real-time OS like FreeRTOS, and a variation of Linux. C++ is the most widely used language in embedded systems programming. It is preferred over C to write complex embedded OS. Since C++ provides re-use ability of code (inheritance) and greater modularity ( classes ), it is much easier to update the software, in advanced versions.Also, C++ is mostly used in critical embedded systems (where reliability is of utmost importance) like auto-pilot, medical devices , etc. C++ is the most reliable language. read less
