What It Is

C++ By Example is a C++ learning website built around “code examples + concise explanations,” written and produced by Rob Cusimano. It is not a traditional video course or bootcamp; it is closer to a modern C++ example library organized by topic. The site lists tags such as beginner, intermediate, advanced, as well as c++11, c++14, c++17, c++20, and c++23, making it easy for learners to find content by difficulty level or language standard.

Core Content and Teaching Format

Based on the available content, the site covers common topics such as arrays, strings, functions, classes, constructors/destructors, exceptions, file I/O, hash tables, sets, sorting, pointers, references, smart pointers, templates, lambdas, vector, and printing standard library containers. The teaching format is mainly web articles and code examples. There is no sign of live classes, recorded video lessons, 1-on-1 tutoring, homework grading, or community Q&A. The site notes that examples typically use the “second newest C++ standard,” while also taking mainstream compiler support into account. It also states that examples are compiled with -Wall -Werror and the relevant standard enabled, which is a plus for code reliability.

Pricing and Certificates

The main content does not mention paid access, subscriptions, memberships, or course bundles, and the site appears to be freely accessible. The code is owned by Rob Cusimano and provided under the MIT license, making it convenient for learners to reference and reuse. There is no information about certification or certificates, so it is not suitable for users who need proof of course completion, professional certification, or corporate training documentation.

Pros and Cons

Its strengths are its lightweight structure and clear topic organization, making it suitable for quickly looking up a specific C++ usage pattern. The content focuses on modern C++ standards, making it more relevant to current development environments than many older tutorials that remain centered on C++98/C++11. The downsides are the lack of a systematic learning path, as well as no visible exercises, projects, quizzes, progress tracking, or Q&A support. For complete beginners, these examples alone may not provide enough continuity; for experienced learners, it works more like an efficient quick-reference resource.

Who It’s For and Access from China

It is suitable for beginner to intermediate C++ learners, especially those who already know the keywords for the problem they are trying to solve and want to quickly see the correct way to write something. Advanced learners can also use it to review the standard library and modern syntax. The source text provides no information about access from China, so this remains unknown; payment cannot be assessed either. If access is unstable, cppreference, learncpp.com, cplusplus.com, or domestic C++ tutorials and university open courses can serve as alternatives and supplements.
