C++ Coding Interview Practice
C++ is the language of performance-critical systems and competitive programming. Many engineers at systems-level companies, game studios, and trading firms are expected to solve interview problems in C++. Its STL provides everything needed for interview problems, and its raw speed can be advantageous in optimization-heavy challenges.
Why C++ for Interviews?
C++ STL is one of the most powerful standard libraries for algorithm problems: vector, unordered_map, priority_queue, set, and deque cover every common data structure. Pointers and references give you precise control, and modern C++11/14/17 features make code more expressive.

C++ Interview Tip
Use auto for type inference, range-based for loops, and structured bindings to keep code concise. Know unordered_map (O(1) avg) vs map (O(log n) sorted). Use priority_queue with greater<int> for min-heaps. Always mention memory management considerations even if not explicitly coding them.
