You need to work with your team members to complete the project, which requires the team members to be part of the project. For example, you might just be responsible for communicating or displaying this one. At this point, you should write your own piece of the program as a module, separate debugging, leaving the interface for other modules to call. Finally, the team members will be responsible for the completion of their own modules and debugging, after the project leader for the combination of debugging. In these cases the procedure must be modular. The benefits of modularity are many, not just for division of labor. It also helps to debug programs, facilitate division of program structures, and increase readability and portability of programs. Beginners often fail to understand how modular programming is, in fact, easy to learn, and one of the most effective ways to organize good program structures This article will first talk about the modular approach and attention, and finally will be the most widely used beginners keil c compiler as an example, given the detailed steps of modular programming. Modular programming should understand the following overview: (1) a module is a combination of an.C file and an.H file, and the header file (.H) is a declaration of the module interface; This article summarizes the modular method and the essence of the realization: a separate function module code written to a.C file, then the interface function of the module in the.H file. For example: if you use liquid crystal display, then you might write a LCD driver module, to realize the character, Chinese characters and images of reality, named as led_device.c, the module of the.C file can be written in general: /******
