此程序是对输入含有待格式化的文本文件进行简单的排版操作。先进行总体设置，文件格式化可分解为页面设计和文本内容设计两大模块，页面设置主要包括页首、页脚、页码标注、页长及页宽参数设定；文本内容的格式主要包括左边距、字间距、左右对齐及段落设置；再进行详细设计，基于C语言编程环境编写各部分子程序，最后将程序连接在一起，进行整体调试，程序运行稳定，时间和空间复杂度低，且所得结果完全符合题目要求。-This program is the input to be formatted text file containing a simple layout operation. First conduct a general setting, the file format page design and text can be decomposed into two modules content design, page set includes top, footer, page tagging, page length and page width parameter settings　text formats include the left distance, word spacing, left aligned, and paragraphs set　further detailed design, based on C language programming environment of molecular procedures for the preparation of various ministries, and finally to connect together, to conduct an overall debugging, program is running stable, time and space complexity is low, and the The results fully in line with the subject requirements.
