模块化编程注意点（Modular programming attention points） Before talking about todays topic, lets talk about some of my previous experiences. At the beginning of exposure to the C language program, due to the limitations of learning content, written procedures are not very large, usually hundreds of lines and carry on. So all the programs are done in a single source file. Remember when freshman participated in an electronic design contest in school, debugging for more than a week, all procedures add up to nearly 1000 lines, a long file, from browsing down, it is better half a day. Mistakes, simple syntax errors, good positioning, some other mistakes, often looking for half a day to find. At that time, I began to know the modular programming, and tried to write the program into modules. Is the beginning of the function of some of the same function (for example, 1602 LCD driver) all written in a header file (.H) file, and then call the place included, but soon discovered that this method has its limitations, it is easy to make mistakes include repeat. And its very inconvenient to call. Soon, the summer of electronic design competition came, the school of our SCM software programming carried out some training. Because the school over the years in country race and race, therefore accumulated a drive module, a certain number of days, every day the teacher will arrange a certain amount of task, let us use these modules together to complete certain functions. And it was those days of modular programming that gave me a better understanding of modular programming. And procedural norms are beginning to take note. Since then, regardless of the size of the program, it has been programmed in modular programming. For a long time, SCM enthusiasts have been on the QQ and I exchange together. Sometimes they send you some source files that have problems and let me help you fix them. The same is a file named long, and is not standardized, look down from the beginning, it is painful to tell the t
