How sublime runs programs

To call C functions in C, you need to use extern "C" to prevent name modification. The specific steps are: 1. Write the C function header file hello.h and wrap extern "C" with #ifdef__cplusplus to ensure compatibility; 2. Implement the C function say_hello() and include the header file in the main program main.cpp of C; 3. Use g to compile the C file and link the C target file or directly compile the link; 4. Run the program to correctly output the results, indicating that the C function was called successfully. The whole process needs to ensure that the declaration and compilation method are correct, and the program can run normally and output "CallingCfunc

Solana is a high-performance blockchain project originated from the United States. With its advantages of high speed and low cost, it has developed rapidly in DeFi, NFT, GameFi and other fields. Its ecosystem relies on centralized and decentralized trading platforms to provide liquidity and trading support, especially in the DEX field. The core technology is a combination of historical proof (PoH) and proof of stake (PoS) to achieve high TPS and low fees, but network stability has been challenged many times.

To debug a remote Python application, you need to use debugpy and configure port forwarding and path mapping: First, install debugpy on the remote machine and modify the code to listen to port 5678, forward the remote port to the local area through the SSH tunnel, then configure "AttachtoRemotePython" in VSCode's launch.json and correctly set the localRoot and remoteRoot path mappings. Finally, start the application and connect to the debugger to realize remote breakpoint debugging, variable checking and code stepping. The entire process depends on debugpy, secure port forwarding and precise path matching.

To list all files in the directory, it is recommended to use C 17's std::filesystem library, which is cross-platform and safe; for example, use std::filesystem::directory_iterator to traverse the directory and filter files through is_regular_file(). When compiling, -std=c 17 must be enabled; POSIX's opendir and readdir can be used with dirent.h implementation in Linux/macOS systems that do not support C 17; Windows APIs such as _findfirst and _findnext can be used on Windows; all three methods need to correctly handle errors

inlinenamespace is mainly used for version control and symbol transparent exposure, and its members can be directly accessed by the outer namespace. ① The name in inlinenamespace is regarded as a direct member of the outer namespace and can be used without specifying the inner namespace; ② It is commonly used for library version management. If v1 is set to inline and is changed to v2 during upgrade, the old version can still be accessed through an explicit namespace; ③ Support ABI compatibility design, the new version type is exposed by default, and the old binary interface is retained in non-inline namespaces; ④ Can be nested and multiple existences, but usually only one is expanded as the default; ⑤ Note that an outer namespace can only have one default inline subnamespace, and users should be avoided

To convert a string to uppercase or lowercase, use the std::transform combined with ::toupper or ::tolower functions. 1. Include header files and; 2. Call std::transform, pass the start and end iterator of the string, and specify the output iterator to str.begin() to modify it in place; 3. Use ::toupper to convert each character to uppercase, or use ::tolower to lowercase. This method is suitable for ASCII strings and the code is simple and efficient. For non-ASCII or Unicode text, libraries such as ICU should be used to ensure proper processing. Although the manual cycle is highly readable, it is less efficient. Therefore, it is recommended to use std::
