C语言用链表实现管理系统
C语言用链表实现电脑配件管理系统
第一次发表Blog,有些问题处理的不是很好，望体谅，同学们可以在评论区询问我相关的问题并指出我的不足。
本人在某偏远地区末流985大学（就是这样：自己的学校只允许自己人喷）软件工程专业学习，大一第一个学期学习了C语言，第二个学期前两个月要求编写C语言完整的管理系统，这个管理系统主要由我和我的一个队友用
发一下大体要求：（具体要求未征询出题老师同意，不方便透露）
补充：
1.我们设定批发时，规定数量50，规定额度5000，如果超过就会出现赠品。
2.在统计金额时，默认初始资金为5，000，000。
遇到的问题有很多，大部分都尝试解决了。下面分享一下编写电脑配件管理系统的要注意的地方与我们的代码，希望对同学们有帮助。
1.（重点）首先一定要仔细读题，理解题目。把题目中的每一个要求都读懂，不要和我们一样，在编程中期时发现我们写的函数有些与题目中的要求不一样，才修改，而且因为程序是一个整体，所以大改会有些麻烦。但是，即使我们又理解了一遍题意，仍然有些地方没有处理好。例如：按照（4）中要求题目中暗示要将配件按照大小型分类，但我们完全没有考虑到这个问题。
2.（重点）一定要先写好主函数，然后在编写每一个分函数，思路要清晰。我发一下我写的主函数，大家可以借鉴一下。
//主函数
int main(int argc, char *argv[]){
system("color F5");//背景颜色
SetConsoleTitle("计算机配件管理系统");//标题
login();//登入函数
while(1)//无限循环
{
switch(menu())//选择函数
{
case 0:
system("CLS");
rewrite();//密码修改函数
break;
case 1:
system("CLS");
gotoxy(55,1);//光标移动函数
printf("*------------------------------计算机配件信息添加-----------------------------*");
add();//添加函数
break;
case 2:
system("CLS");
money();//可以实时改变的统计金额函数
gotoxy(55,6);
printf("*------------------------------计算机配件信息修改-----------------------------*");
revise();//修改函数
break;
case 3:
system("CLS");
gotoxy(55,6);
printf("*------------------------------计算机配件信息删除-----------------------------*");
Delete();//删除函数
break;
case 4:
system("CLS");
money();
gotoxy(55,6);
printf("*-------------------------按照顺序排序生成目前库存报表-----------------------*");
queryone();//库存函数
break;
case 5:
system("CLS");
money();
gotoxy(55,6);
printf("*-------------------------按照时间排序成目前库存报表-----------------------*");
querytwo();//按照时间排序
break;
case 6:
system("CLS");
money();
gotoxy(55,6);
printf("*-------------------------计算机配件信息查询(顺序排序)-----------------------*");
choice();//查询函数
break;
case 7:
system("CLS");
money();
gotoxy(55,2);
printf("*------------------------------计算机配件统计赠品-----------------------------*");
statisticsfour();//统计赠品函数
break;
case 8:
system("CLS");
money();
gotoxy(55,1);
printf("*---------------------------计算机配件进货时间查询----------------------------*");
timequery();//时间查询函数
break;
case 9:
system("CLS");
end();//结束函数
break;
}
}
return 0;
}
3.程序中出现名称的地方尽量用英语来表示，用汉语拼音来表示感觉有点难受（个人观点）。（我们写到大概三分之一时，发现了这个问题，改的时候也比较麻烦）
4.一定要写注释，有的同学为了省事，注释写的很少，这会影响程序的可读性，而且以后自己想要修改也会有些麻烦。我们也做的不好，前期写的还挺多，后期也懒得写了。(但我会在我的博客上慢慢增加的)
完整代码
（分函数按照在主函数中出现的顺序排列）
下面分享一下我们写的完整代码与运行过程图片，再之后会在之后我的Blog中对我感觉重要的函数进行讲解。（按照具体要求，我们不需要在程序中创建文本文件，所以要求我们提前在外部C语言程序所在文件中创建好txt文件，而且要在不同的txt文件中按照规定的格式（在写入文件函数中寻找）输入至少一条信息，当然，这些样本文件我也会上传到我的Blog上【估计两三天以后就会审核通过】，如果大家想直接运行程序，可以先下载并将其移动其到正确位置即可运行）

接下来是程序运行过程截图
提醒：截图没有把此程序的全部功能体现出来，有些功能需要自己切实操作才能完美体现。
总结
忙了一个多月，学的东西也基本用上了，只要链表，文件会的话，写一个简单的管理系统也是比较简单的，希望对大家有帮助，本人也要学新东西了（但只要有时间就会对这个程序修改完善，关注我的Blog,后续会陆续发表相关信息）。其实还有很多功能自己没写，比如多端登陆，多线程运行，图形界面，弹窗提醒等等，跟别人的差距还是蛮大的。
补：上传文件有些麻烦，我就直接把样本文件直接写出来吧
