embedded-systems-prep

Comprehensive embedded systems preparation — C core concepts, C++ interview notes, data structures & algorithms, operating systems, embedded drivers, system design, and more.

The repo keeps language references split by focus: c_core/ for C fundamentals and cpp_core/ for C++ interview-oriented notes and STL references.
