要开发一个C应用程序（.exe文件），大体上分为5个步骤（不考虑后期维护）：
问题分析――分析要解决的问题，明确问题目标，将问题（尤其是复杂问题）分解为在数据、
-To develop a C application (. Exe file), generally divided into five steps (without regard to post-maintenance): Problem Analysis- Analysis of issues to be addressed explicitly the issue of targets, the problem (in particular, are complex issues) is decomposed into in the data,
