Modern C++
Chào mừng đến với Modern C++ - nơi bạn học C++ theo cách của thế kỷ 21, với C++11/14/17/20/23 và best practices từ production systems.
Tại Sao Học C++?
C++ không chỉ là ngôn ngữ "khó" hay "legacy". Nó là:
- ⚡ Performance King: Fastest execution speed, zero-cost abstractions
- 🎮 Game Development: Unreal Engine, Unity (core), AAA games
- 🚀 Systems Programming: Operating Systems, Browsers, Databases
- 🤖 Embedded Systems: IoT, Robotics, Automotive
- 💰 High-Frequency Trading: Microsecond latency matters

Lời khuyên từ Professor Tom
Modern C++ ≠ Old C++. Đừng học C++ theo sách cũ. Sử dụng C++17/20 features, smart pointers thay vì raw pointers, và luôn compile với -std=c++20 -Wall -Wextra.
