C++ Interview Questions & Assessment
Assess C++ skills including memory management, templates, STL, modern C++ features (C++17/20), and performance optimization.
Why C++ Matters
C++ remains essential for game engines, operating systems, embedded systems, high-frequency trading, and performance-critical applications where microseconds matter.
