Directory Structure

The whole project according to the functional modules delimited molecular directory, each subdirectory and then divided header file and source file directory, so that the architecture is clear and easy to understand.

Directory Design

Principle

The naming of the directory should accurately describe the basic function of the module, it is recommended to use lowercase letters and do not contain underline, dot and other special symbols;

Directories must be placed under the parent directory that they contain, and they need to be explicitly coupled to other directories.

Dependencies

Principle

New components are often dependent on existing components of the system, and the components that are directly dependent must be specified with minimal coupling.

Header File

Naming

Principle

Header file naming should accurately describe the contents of the module contained in the file to achieve the purpose of easy to understand.
