职工工资管理系统
暑假学校实习，要求做个工资管理系统。写这篇博客来记录下过程，以及在做的过程中的一些总结！提前说下这是基于C语言写的管理系统！
话不多说，先上图介绍下有哪些功能！
1.首先来开下数据结构吧
#define N 100
struct Worker
{char workernum[10];//员工编号char workername[20];//员工姓名int basicwage;//员工基本工资int allowance;//津贴int Bonus;//员工工资int totalwage;//员工总工资
}Worker_Infor[N];
struct Worker temp;
int m;//定义全局变量控制人数
结构体数组这块没啥太多东西，一些员工的基本属性就OK了,其实在这里本来想用动态数组的但是C语言这学期学完后没往深了看，就没使用动态赋值！?
2. ? 看看第一个功能吧，信息录入。这个功能比较好弄，而且方法也比较多。
那就不多说了，上代码！
void Input_Infor()
{char c,nums[20];int i,j,flag=1;if(m==0)i=0;else i=m;printf(" ------------------------| 员工信息录入 |------------------------------\n");printf(" ======================================================================\n");while(1){printf(" || -第%d位职工的编号:",i+1);TO:if(m==0){gets(Worker_Infor[m].workernum);}else{gets(nums);for(j=0;j<m;j++){if(strcmp(nums,Worker_Infor[j].workernum)==0){printf(" || -已存在！请重输:");goto TO;}else{strcpy(Worker_Infor[i].workernum,nums);}}}printf("\n || -工号为%s职工的姓名:",Worker_Infor[i].workernum);gets(Worker_Infor[i].workername);printf("\n || -%s职工基本工资:",Worker_Infor[i].workername);while(1){scanf("%d",&Worker_Infor[i].basicwage);if(Worker_Infor[i].basicwage>=0) break;else printf("\n || 输入错误,请重试:");}printf("\n || -%s职工的津贴:",Worker_Infor[i].workername);while(1){scanf("%d",&Worker_Infor[i].allowance);if(Worker_Infor[i].allowance>=0) break;else printf("\t输入错误,请重试:");}printf("\n || -%s职工的奖金:",Worker_Infor[i].workername);while(1){scanf("%d",&Worker_Infor[i].Bonus);if(Worker_Infor[i].Bonus>=0) break;else printf("\t输入错误,请重试:");}i++;m=i;getchar();printf("\n || -是否继续输入:Y or N 或者 y or n:");scanf("%c",&c);getchar();if(c=='N'||c=='n'){system("cls");printf(" =========================================================================================\n");printf(" || ||\n");printf(" || 感谢您的使用！ ||\n");printf(" || ||\n");printf(" || 信息更新完毕请保存! ||\n");printf(" || ||\n");printf(" || - @author by---Zdde丶 - ||\n");printf(" =========================================================================================\n");break;}}
}
这部分有一个点，就是在录入编号的时候，要检查数据文件里面是否有重复的。开始弄这个时觉得这个功能很简单，想着用个while（1）循环里面套for循环，遍历结构体数组。也就是把现在代码里面的goto换成了while（1）来做的，结果出现了一个很不可思议的问题，就是if else语句居然if和else里面的东西同时满足并且执行了。后来也发现了问题所在。但是这个问题真的很隐蔽。
3. 再就是保存数据到硬盘的功能了
保存文件就用到了C语言的文件管理。课堂上老师也就一笔带过，再弄这块也是疯狂的百度资料。
主要是查询fread fwrite ，fscanf以及fprintf这四个函数的用法。想来想去还是用了fscanf和fprintf这两个。毕竟是刚自学不久，我就不讲二者用法了。上代码看看这个功能吧
void Save_Infor()
{int i,n=0;FILE *pk;FILE *pf;Cal_Wages();pk=fopen("Worker.txt","w");pf=fopen("sumpeo.txt","w");n += m;//这里其实是多余的直接使用m即可fprintf(pf,"%d",n);if(pk==NULL||pf==NULL);{printf("文件打开失败\n");exit(0);}for(i=0;i<m;i++){fprintf(pk,"\t%10s\t%8s\t%10d\t%8d%8d%6d\t\n",Worker_Infor[i].workernum,Worker_Infor[i].workername,Worker_Infor[i].basicwage,Worker_Infor[i].allowance,Worker_Infor[i].Bonus,Worker_Infor[i].totalwage);}fclose(pf);fclose(pk);printf(" =======================================================================================\n");printf(" || ||\n");printf(" || 文件保存成功 ||\n");printf(" || ||\n");printf(" =======================================================================================\n");}
保存文件这块，也就这点代码，但是真的让我查了很久的资料！
4.数据载入
功能快捷键
int Up_infor()
{FILE *fp;FILE *pk;int i;fp = fopen("Worker.txt","r");pk = fopen("sumpeo.txt","rb");if(pk==NULL){printf(" =======================================================================================\n");printf(" || ||\n");printf(" || 文件打开失败 ||\n");printf(" || ||\n");printf(" =======================================================================================\n");}else{fscanf(pk,"%d",&m);//printf("%d",m);}for(i=0;i<m;i++){fscanf(fp,"\t%10s\t%8s",Worker_Infor[i].workernum,Worker_Infor[i].workername);fscanf(fp,"\t%10d\t%8d%8d%6d",&Worker_Infor[i].basicwage,&Worker_Infor[i].allowance,&Worker_Infor[i].Bonus,&Worker_Infor[i].totalwage);}return m;fclose(fp);fclose(pk);}
这里使用了两个txt文件，一个是保存人数，一个是保存每个人的信息。这里函数返回了一个整型值m，为的就是开始定义的全局变量m能够起作用。我想的是，将人数保存在单独的文件中，每次从文件中读取，就可以在全局使用这个人数了，因为人数就可以控制for循环的范围，便于遍历数组。
5.这里也就不一个一个去说了。直接上全部代码和调试截图
