Sams Teach Yourself C++ in 21 Days (7th Edition)

C++ in One Hour a Day, 7th Edition, is the Chinese translation of the seventh edition of Sams Teach Yourself C++ in One Hour a Day, translated by Yuan Guozhong and Yang Xiaoke. Structured around a one-hour-a-day pace, the book's 29 chapters break down the core knowledge of C++ and the new features of C++11 into compact units that can each be read in an hour. Every chapter includes sample programs, output results, and code analysis, and closes with a Q&A, quiz, and exercises, with answers collected in Appendix D for convenient self-assessment. The content starts from the very basics: the history of C++ and the compilation and execution process, the fundamental components of a program, variables and constants, arrays and strings, expressions and operators, flow control, functions, pointers and references. It then moves into object-oriented programming, covering classes and objects, inheritance, polymorphism, operator overloading, and type-conversion operators. Further chapters introduce macros and templates, the Standard Template Library (containers such as string, vector, list/forward_list, set, and map, along with function objects), lambda expressions, STL algorithms, adaptive containers such as stacks and queues, bit flags, smart pointers, and stream-based input/output and exception handling. The final chapter offers guidance on learning paths and directions for further study. The book assumes no prior C background and serves both as a textbook for university C++ courses and as an introductory self-study guide.
