C language development standard specification link

The following are some commonly used C language development standard specification links:

1. GNU C programming specification: https://www.gnu.org/prep/standards/html_node/index.html

2. Google C++ Style Guide (also applies to C): https://google.github.io/styleguide/cppguide.html

3. Linux Kernel Programming Style Guide: https://www.kernel.org/doc/html/latest/process/coding-style.html

4. CERT C Coding Standard: https://wiki.sei.cmu.edu/confluence/display/c/SEI+CERT+C+Coding+Standard

Note that while some of the specifications in the above link are for C++ or a specific project, most of them apply to C as well. In actual development, you can choose the applicable specification according to your own needs and project requirements, and adjust and maintain it according to the agreement of the team.
