 International students will be given timeslot for C programming features online live demonstrations through embedded applications as per their preferred timezone.

    C is just a step up from assembly language, which is practically a hexadecimal human translation of machine code and considered the lowest level programming language. Hence programming, debugging and maintaining C code when applied to embedded software/firmware applications can be a nightmare if not practiced properly. Following industry standard programming exercises, solutions, live embedded feature demonstrations using software and firmware development boards will give you the real development experience for your competitive exams, interviews and career.
