Summary

This book offers beginners a comprehensive introduction to C++, covering the language's fundamentals in a systematic way. It comprises 6 parts and 21 chapters. Part 1, C++ Data Representation, covers C++ basics, variables and data types, operators and expressions, and program control structures. Part 2, Procedural Programming in C++, covers functions, preprocessing directives, arrays, pointers, and constructed data types. Part 3, Object-Oriented Programming in C++, covers classes and objects, inheritance, polymorphism, operator overloading, and input/output streams. Part 4 introduces advanced C++ features, including files, namespaces, references, and memory management. Part 5 focuses on C++ programming practice, analyzing the Standard Template Library (STL), templates and the C++ standard library, and exception handling. The final part uses a student grade management system as a case study to explain how to develop real applications with C++. This book is suitable as an introductory tutorial for C++ beginners with no programming background, as a textbook for university faculty and students and training courses, and as a valuable reference for C++ enthusiasts.

Editor's review

21 Days to Learn C++ (5th Edition) is the latest edition in the classic beginner's programming tutorial series from Publishing House of Electronics Industry, written by Liu Lei. The book continues the series' practical, fast-paced approach, aiming to help readers with little or no prior experience quickly master C++ core syntax and object-oriented programming concepts through a structured 21-day learning plan. Compared with previous editions, the 5th edition has been updated to keep pace with current practice: it covers some C++11/14 features and expands practical topics such as development environments and debugging techniques, making the knowledge framework better aligned with the real needs of modern software development.

From an editorial perspective, the book's greatest value lies in its carefully designed step-by-step learning curve. It breaks the vast C++ knowledge system into digestible daily modules, each chapter providing clear example code and end-of-chapter exercises. This learn-by-doing model effectively reduces beginners' anxiety and promotes immediate consolidation of knowledge. Author Liu Lei is experienced in technical education, and her plain, clear prose is particularly good at explaining complex concepts through analogy (for example, comparing classes and objects to blueprints and houses), helping readers build intuitive understanding.

It should be noted, however, that the "21 days" in the title is more of an idealized learning path than a guarantee. C++ is known for its depth and complexity, and true proficiency requires sustained practice and project work well beyond 21 days. The book is therefore best used as a guide from beginner to capable practitioner, helping readers build a solid knowledge skeleton and laying the groundwork for further exploration of advanced topics such as the standard library and template metaprogramming. For readers who want a systematic introduction to C++ and prefer a structured learning pace, this is a reliable and practical choice.

Who it's for

A good fit for

Complete beginners who want to learn C++ programming systematically
Programmers with experience in other languages (such as C or Java) who want to move quickly into C++ development
Self-learners who need a clearly structured tutorial with daily tasks to stay motivated
University students in computer-related majors, as a course companion or preview material

Not a good fit for

Experienced developers seeking in-depth analysis of advanced C++ features (such as template metaprogramming and the concurrency memory model)
Extreme hands-on learners who prefer project-driven learning and dislike step-by-step approaches

Reading tips

Follow the daily plan strictly and be sure to run all example code and complete the exercises; programming skills improve only through repeated hands-on practice
Study with a stable IDE (such as Visual Studio or Code::Blocks); read the environment setup sections carefully
When studying the object-oriented chapters, don't try to understand every concept at once; grasp the basics first and deepen your understanding through later exercises

FAQ

Can this book really teach someone C++ in 21 days?

"Learn" is relative. The book can help you systematically grasp C++ core syntax, object-oriented programming basics, and essential programming concepts within 21 days, to the point where you can write simple programs and understand common code. But becoming proficient, let alone mastering the language, inevitably requires further project practice and deeper study beyond this foundation.

What are the main updates in the 5th edition compared with older editions?

The main updates in the 5th edition are the introduction of some C++11/14 features (such as auto type deduction and range-based for loops), a more modern introduction to development environments, corrections of some oversights in previous editions, and improvements to some examples and exercises to better match current learning and development habits.

I have absolutely no background and am weak in math and English. Can I understand this book?

The book is written with complete beginners in mind. It requires very little math—mainly basic logic. The English keywords needed for programming are limited and fixed, and the book explains them one by one. As long as you have basic computer skills and a persistent attitude, you can certainly get started with this book.

About the author

刘蕾 Author

Liu Lei is a Chinese book author whose works span two quite different fields: agriculture and forestry, and programming and design. Public information about her is limited, and her nationality, dates of birth and death, and English name have not been clearly recorded. Judging from the three works included in the collection, her writing is clearly practical and introductory in orientation. On the one hand, she contributed to Understanding Chinese Plants: South China Volume, a book intended for plant identification and popular science reading. On the other hand, she is the author of Teach Yourself C in 21 Days (5th Edition) and Teach Yourself C++ in 21 Days (5th Edition), which guide beginners through programming fundamentals in a step-by-step, day-by-day format. Though the two categories are far apart, both stress concrete presentation of knowledge and hands-on usability for readers. Overall, Liu Lei's writing focuses on popularization and instruction, suited to beginners who wish to learn in a structured way, and offers practical reference value to readers in these areas.
