Modern C++:
Power, Elegance, Control.
From embedded systems to AAA games and AI inference, C++ remains the backbone of performance‑critical software.

Modern Syntax
C++11–C++23: auto, ranges, concepts, constexpr, coroutines, modules.
Zero-cost Abstractions
High-level APIs that compile down to optimal machine code.
Performance & Control
Memory/layout control, SIMD, parallelism, cache-friendly design.
Portability
From microcontrollers to supercomputers and every OS in between.
Interoperability
Seamless FFI with C, Rust, Python bindings, CUDA/HIP for GPUs.
Tooling
Clang/LLVM, GCC, MSVC, CMake, Conan/Vcpkg, Sanitizers, LSP.
Why the world still needs C++
Deterministic performance
Manual control over memory and execution makes it ideal for latency‑sensitive systems.
Longevity & stability
Decades of compatibility and a standards committee advancing the language safely.
Ecosystem maturity
Battle‑tested libraries, build systems, and profilers across all major platforms.
Ubiquity
Used in browsers, databases, game engines, finance, embedded OSes, robotics, ML runtimes.
Where C++ dominates
Game Engines
Unreal Engine, idTech — real-time rendering, physics, and tooling.
Finance/HFT
Ultra-low latency trading, risk engines, market data processing.
AI & HPC
Inference runtimes, CUDA kernels, scientific simulations, HPC frameworks.
Embedded & IoT
Deterministic, tiny-footprint systems with realtime constraints.
Browsers & OS
Chromium subsystems, OS kernels, filesystems, drivers, desktop apps.
Databases
RocksDB, ClickHouse engines, high-throughput storage and indexing.
Performance, visualized
Benchmarks vary by workload, hardware, and compiler flags. But across domains, C++ consistently delivers top-tier performance with predictable latencies. For reproducible numbers, build micro-benchmarks with google/benchmarkand profile with perf/VTune/Tracy.
