The structure and specification of a complete project in C usually includes the following sections:
Header Files: Header files contain the declarations of various functions, variables, macro definitions, etc. required in the program, as well as references to various library functions. Usually with the extension of .h, it can be included in and used by other source files.
Source Files: Source files contain the implementation code of the program, usually with a .c extension, which can be compiled into an object file alone, or linked together with other source files into an executable file.
Library files (Library Files): Library files are a collection of precompiled object files that contain a large number of implementation codes for functions and variables that can be linked into programs for use.
Makefile: Makefile is a script file for compiling programs, which can automate the compilation process and avoid errors and repeated operations during manual compilation.
Documentation: Documentation includes program descriptions, manuals, user manuals, etc., and is usually written in the format of README.md, which can help users better understand and use the program.
A complete C language project is usually organized according to the following structure:
project/
├── include/
│ ├── header1.h
│ └── header2.h
├── src/
│ ├── file1.c
│ └── file2.c
├── lib/
│ ├── lib1.a
│ └── lib2.a
├── Makefile
├── README.md
└── LICENSE
Among them, the include directory stores header files, the src directory stores source files, and the lib directory stores library files. Makefile is used to compile the program, README.md is used to explain the information and usage of the project, and LICENSE is used to explain the copyright and license information of the project.
When implementing a C language project, the above structure and description can be used for reference, and adjustments and extensions can be made according to specific situations.
