3.预处理模块设计1.经过思考，我决定以下滑菜单的形式设计主界面，我通过查资料，获悉了getch函数的使用方法，并想出了用计数变量choice来计算菜单偏离数，然后将choice取模5得到which，以此得到用户选择了哪个子菜单，而子菜单用同样的方式确定如何进入下级菜单。

同时，每一个获取的分支结构都套在while(1)的循环中，用break语句与其组合，实现从下级菜单向上级菜单的后退，这样就避免了使用goto语句而造成的内存问题。

3.1.文件引用Stdio.hWindows.hStdlib.hConio.h3.2.宏定义#define maxname 503.3.定义全局变量struct book{int num;char name[50];char aname[50];int sortnum;char bname[20];int time;float value;};3.4.函数声明（1）char *s_gets(char *st, int n)输入参数：字符型指针st，整型常量n，输出参数：字符型常量s实现功能：清空输入行，替换fgets函数中自动添加的换行符，以改良fgets 函数的功能，同时避免了使用gets函数的不安全问题（2）void gotoxy(int x, int y)输入参数：整型常量x与y输出参数：无实现功能：获得控制台句柄，定位x、y，以实现跳转到某位置进行输入4.系统欢迎界面设计4.1.系统欢迎界面设计概述系统的开始界面分为五大部分，分别为图书信息的录入、图书信息的修改、图书信息的删除、图书信息的搜索、显示全部图书信息4.2.设置文字颜色通过这条语句定义句柄结构体：HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);先用这行语句将标准输出文字的形式设置为蓝底白字，模拟菜单选中时的效果：SetConsoleTextAttribute(hConsole,BACKGROUND_BLUE|FOREGROUND_GREEN|FO REGROUND_RED | FOREGROUND_BLUE);再用这行语句将文字形式设回黑底白字，进行下面的输入：SetConsoleTextAttribute(hConsole,FOREGROUND_GREEN|FOREGROUND_RED|FOR EGROUND_BLUE);最终得到的效果如下：4.3.设置文字显示位置用空格和换行符将文字设置为居中显示5.退出系统关闭即可，已设置为自动保存6.项目创新点创新点在于将上下键控制的菜单以c代码形式设计出来，把并且实现了在最下或最上选项在向下（上）按时实现了回跳，而且通过操纵控制台句柄实现了标准输出颜色的更改7.收获和建议通过独立完成这个图书馆管理系统，我积累了查找资料并运用资料中的知识在自己的程序中实现的能力，同时对句柄的使用也让我对shell的理解更为深入，也理解了控制台与我们日常所见程序的不同，而这也让我理解了为什么c是贴近底层的语言，附：源代码清单#include <stdlib.h>#include <stdio.h>#include <conio.h>#include <windows.h>//#include <time.h>#define maxname 50struct book{int num;char name[50];char aname[50];int sortnum;char bname[20];int time;float value;};void gotoxy(int x, int y)//用于获取控制台句柄，实现光标回退{COORD pos = {x, y};HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
