Modern C++ Fast Track

Modern C++ Fast Track is a practical guide for developers who want to build stronger C++20 and C++23 programs without getting lost in isolated language details.

This book focuses on the habits that matter in real projects: clear ownership, RAII, value semantics, smart pointers, STL containers and algorithms, concepts, ranges, error handling, memory safety, concurrency, performance-aware design, and practical command-line projects.

Readers will learn how to design safer types, avoid common lifetime bugs, use the standard library effectively, write clearer generic code, approach threading carefully, and measure performance before optimizing. The book also includes hands-on project chapters covering a file word indexer, a concurrent log analyzer, and a binary packet parser.

This is a focused, practical fast-track book for programmers who want to move from basic C++ knowledge toward cleaner, safer, more modern software development.
