1. Probably the best job interview website on the Internet

Some time ago, I discovered a good job interview website, which can screen real interview questions based on designated industries, companies, interview positions, subjects, and inspection times . It also includes the most recent inspection time and cumulative number of inspections .

It’s simply a great artifact ! ! ! For example, I want to check what are the interview questions such as the industry is the Internet, the company is ByteDance, the position is back-end, the subject is not limited, and the inspection time is within the past year?

In addition to the Internet, the industries include state-owned enterprises, banks, foreign companies and other industries. As of the time I found out, it was like this. It seems that the website is gradually adding new data in the later period.

Take the Internet as an example. All major domestic and foreign first- and second-tier companies cover it, such as ByteDance, Alibaba, Tencent, Baidu, Meituan, etc.

I would like to share this website here. Such good things cannot be kept secret. If it is helpful to you, giving it a like is the greatest support! ! Thank you!

Probably the most user-friendly C++ learning route

Isn't this the nanny-level C++ learning route you want?

C language ->C with class -> C++; It can be seen from the evolution of C++ that C++ was originally a C language with classes. What is the relationship between C language and C++?
If you have watched Teacher Hou Jie’s video or the book "Effective C++", you will know that when we talk about C++ nowadays, we should regard it as a huge "language federation", which at least contains the following important components:

process oriented programming
object-oriented programming
Generic programming
metaprogramming
functional programming
STL standard library

Among them, "procedural-oriented programming" is the backward-compatible part of the C language provided by C++.

C++ related books (with PDF resources included)

Book recommendations:

"C++ Primer Chinese Edition" is a very friendly self-study textbook for beginners of C++ language. The author clearly explains the basic concepts of C language and the programming details that need to be paid attention to, and is rich in routines and exercises. I believe that after reading it carefully, you can complete the goal of getting started with C language.
"Guide to High-Quality Programming", recommended by Wall Crack. This book is quite enjoyable to read. It contains some programming standards. It is good for people who write programs. It can cultivate good coding habits and deepen their knowledge. Consolidation of some knowledge. It is more practical and suitable for reading before the interview.
"Essential C++ Chinese Edition" is a small but very practical introductory book on C++, emphasizing quick start and understanding of C++ programming. This book focuses on a series of increasingly complex programming problems and the language features used to solve them. You will not only learn the functions and structures of C++, but also their design purpose and basic principles.
"More Effective C++ (Chinese Edition)", this book focuses on 55 principles, each of which introduces a method that allows you to write better C++ program code, and discusses it in detail with specially designed examples.
"Programming Techniques to Improve C++ Performance", this book believes that 20% of performance defects will take up 80% of our time. So we focus our efforts where we have the most value. This book discusses in detail temporary objects, memory management, inheritance, virtual functions, inlining, reference counting, STL and other details that may improve the efficiency of C++. Whether you are a practitioner in a related field, a C++ programming enthusiast, or a programming enthusiast eager to break through programming bottlenecks and greatly improve your self-cultivation, this book will definitely benefit you a lot.
"Learning C/C++ from Defects" is essentially a collection of C/C++ incorrect questions. The book includes 63 errors caused by the problem, which are flaws in the title. It is also a guide for avoiding pitfalls.
"C++ Templates Chinese Edition" is a practical book with an in-depth understanding of modern C++ templates. Not only is this book the authoritative explanation of C++ templates, but it also provides an in-depth introduction to other general C++ ideas.
"STL Source Code Analysis" provides a detailed understanding of the underlying implementation mechanism of STL, and can also have a deeper understanding of common data structures and C++ memory management.
There are also "C++ Standard Library (2nd Edition)", "C++ Concurrent Programming Practice", "C++ Programming Thoughts (Two Volumes)", etc. I bought all the books introduced, but to be honest, the following few I took a general look at this book and used it as a reference book.

FreeNOS: In-depth understanding of C++ and operating system principles. FreeNOS (Free Niek's operating system) is a microkernel-based learning operating system based on C++. This is a microkernel operating system implemented in C++. The services in various macrokernels are treated as independent services in the microkernel, using a message-based communication method. This is actually similar to the mach mechanism in the mac kernel.
Boost: The Boost library is a well-tempered, portable, and source-coded C++ library. As a backup to the standard library, it is one of the engines of the C++ standardization process. The Boost library was initiated by members of the C++ Standard Committee Library Working Group and has a great influence in the C++ community, with nearly 2,000 members. The Boost library brings us the latest, coolest, and most practical technology, and is an out-and-out "accurate" standard library.
Muduo: A modern C++ network library based on the Reactor mode. It adopts a non-blocking IO model, is event-driven and callback-based, supports multi-core and multi-threading, and is suitable for writing Linux server-side multi-threaded network applications.

wfrest: A simple and efficient C++11 asynchronous RESTful network framework.
workflow: currently the most popular, simple and easy-to-use c++ asynchronous network library workflow.
modern-cpp-tutorial: modern-cpp-tutorial is a modern C++ tutorial, its purpose is to provide a comprehensive introduction to the relevant features of modern C++ (pre-2020).
MyTinySTL: A small STL (container library + algorithm library) rewritten in C++11. The code structure is clear and standardized, contains Chinese documentation and comments, and comes with a simple testing framework, which is suitable for C++ novices to practice.
Tinytetris: Tinytetris is a terminal version of the Tetris game written in C++. It provides two versions of source code, divided into annotated version and library version. There are many comments and it is easy to understand and learn.
