Exploring the Hidden Utility of C Private Inheritance
C private inheritance, unlike its protected counterpart, has gained prominence in modern development. However, its practical applications often remain unclear. This article delves into various scenarios where private inheritance proves to be a valuable tool.
According to a developer, private inheritance finds multiple uses:
1. Selective Interface Exposure:
Private inheritance allows for exposing a limited subset of a base class's interface. Public inheritance would falsely suggest inheritance, violating Liskov substitutability. Composition, on the other hand, necessitates the creation of forwarding functions, adding boilerplate code.
2. Safe Derivation from Concrete Classes:
When inheriting from a concrete class lacking a virtual destructor, public inheritance risks undefined behavior if deleted via a pointer-to-base. Private inheritance prevents this by prohibiting such deletions.
3. Deriving Privately from STL Containers:
To utilize specific functions from an STL container without exposing the entire interface, private inheritance can be employed. This approach minimizes code duplication and maintains a clean separation of concerns.
4. Implementing the Adapter Pattern Internally:
Private inheritance aids in implementing the Adapter Pattern by allowing inheritance from the Adapted class without the need for an enclosed instance to which methods are forwarded.
5. Creating Private Interfaces:
Private inheritance facilitates the creation of private interfaces. For instance, it enables an Observer class to subscribe itself to a Subject without revealing the Observer interface to the rest of the system.

People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5

As a beginner graphical programming for C programmers, OpenGL is a good choice. First, you need to build a development environment, use GLFW or SDL to create a window, load the function pointer with GLEW or glad, and correctly set the context version such as 3.3. Secondly, understand OpenGL's state machine model and master the core drawing process: create and compile shaders, link programs, upload vertex data (VBO), configure attribute pointers (VAO) and call drawing functions. In addition, you must be familiar with debugging techniques, check the shader compilation and program link status, enable the vertex attribute array, set the screen clear color, etc. Recommended learning resources include LearnOpenGL, OpenGLRedBook and YouTube tutorial series. Master the above

C STL is a set of general template classes and functions, including core components such as containers, algorithms, and iterators. Containers such as vector, list, map, and set are used to store data. Vector supports random access, which is suitable for frequent reading; list insertion and deletion are efficient but accessed slowly; map and set are based on red and black trees, and automatic sorting is suitable for fast searches. Algorithms such as sort, find, copy, transform, and accumulate are commonly used to encapsulate them, and they act on the iterator range of the container. The iterator acts as a bridge connecting containers to algorithms, supporting traversal and accessing elements. Other components include function objects, adapters, allocators, which are used to customize logic, change behavior, and memory management. STL simplifies C

STL (Standard Template Library) is an important part of the C standard library, including three core components: container, iterator and algorithm. 1. Containers such as vector, map, and set are used to store data; 2. Iterators are used to access container elements; 3. Algorithms such as sort and find are used to operate data. When selecting a container, vector is suitable for dynamic arrays, list is suitable for frequent insertion and deletion, deque supports double-ended quick operation, map/unordered_map is used for key-value pair search, and set/unordered_set is used for deduplication. When using the algorithm, the header file should be included, and iterators and lambda expressions should be combined. Be careful to avoid failure iterators, update iterators when deleting, and not modify m

Learn C You should start from the following points when playing games: 1. Proficient in basic grammar but do not need to go deep into it, master the basic contents of variable definition, looping, condition judgment, functions, etc.; 2. Focus on mastering the use of STL containers such as vector, map, set, queue, and stack; 3. Learn fast input and output techniques, such as closing synchronous streams or using scanf and printf; 4. Use templates and macros to simplify code writing and improve efficiency; 5. Familiar with common details such as boundary conditions and initialization errors.

In C, cin and cout are used for console input and output. 1. Use cout to read the input, pay attention to type matching problems, and stop encountering spaces; 3. Use getline(cin, str) when reading strings containing spaces; 4. When using cin and getline, you need to clean the remaining characters in the buffer; 5. When entering incorrectly, you need to call cin.clear() and cin.ignore() to deal with exception status. Master these key points and write stable console programs.

std::chrono is used in C to process time, including obtaining the current time, measuring execution time, operation time point and duration, and formatting analysis time. 1. Use std::chrono::system_clock::now() to obtain the current time, which can be converted into a readable string, but the system clock may not be monotonous; 2. Use std::chrono::steady_clock to measure the execution time to ensure monotony, and convert it into milliseconds, seconds and other units through duration_cast; 3. Time point (time_point) and duration (duration) can be interoperable, but attention should be paid to unit compatibility and clock epoch (epoch)
