C語言程序設計-職工信息管理系統?一、系統概述職工信息管理系統是一個用于管理職工基本信息、考勤記錄、工資信息等的綜合系統。通過該系統，企業或組織能夠方便快捷地對職工信息進行錄入、查詢、修改、刪除等操作，提高管理效率，確保職工信息的準確性和完整性。

二、功能需求1.職工信息錄入：能夠錄入職工的基本信息，包括姓名、性別、年齡、部門、職位等。2.職工信息查詢：可以根據職工編號、姓名等條件查詢職工的詳細信息。3.職工信息修改：針對已有的職工信息，能夠修改其相應字段的值。4.職工信息刪除：允許刪除指定職工的信息。5.考勤記錄管理：記錄職工的考勤情況，如出勤、請假、曠工等，并能進行統計分析。6.工資信息管理：管理職工的工資信息，包括基本工資、績效工資、獎金等，并能計算出每月的總工資。7.數據存儲與讀取：將職工信息、考勤記錄和工資信息等數據存儲到文件中，并能在程序啟動時讀取這些數據，以便繼續操作。

三、系統設計

數據結構設計1.職工結構體```ctypedefstruct{intid;charname[20];chargender[5];intage;chardepartment[20];charposition[20];}Employee;```2.考勤結構體```ctypedefstruct{intid;chardate[10];charstatus[10];//出勤、請假、曠工等}Attendance;```3.工資結構體```ctypedefstruct{intid;floatbasicSalary;floatperformanceSalary;floatbonus;floattotalSalary;}Salary;```

模塊設計1.主菜單模塊：顯示系統的主要功能選項，如錄入、查詢、修改、刪除等，并根據用戶選擇調用相應的子模塊。```cvoidmainMenu(){intchoice;do{printf("\n職工信息管理系統\n");printf("1.職工信息錄入\n");printf("2.職工信息查詢\n");printf("3.職工信息修改\n");printf("4.職工信息刪除\n");printf("5.考勤記錄管理\n");printf("6.工資信息管理\n");printf("0.退出系統\n");printf("請選擇:");scanf("%d",&choice);

switch(choice){case1:addEmployee();break;case2:searchEmployee();break;case3:updateEmployee();break;case4:deleteEmployee();break;case5:attendanceManagement();break;case6:salaryManagement();break;case0:printf("退出系統\n");break;default:printf("無效選擇，請重新輸入\n");}}while(choice!=0);}```2.職工信息錄入模塊：提示用戶輸入職工的各項信息，并將其存儲到數組或文件中。```cvoidaddEmployee(){Employeeemp;FILE*fp;fp=fopen("employees.txt","a");if(fp==NULL){printf("文件打開失敗\n");return;}printf("請輸入職工編號:");scanf("%d",&emp.id);printf("請輸入職工姓名:");scanf("%s",);printf("請輸入職工性別:");scanf("%s",emp.gender);printf("請輸入職工年齡:");scanf("%d",&emp.age);printf("請輸入職工部門:");scanf("%s",emp.department);printf("請輸入職工職位:");scanf("%s",emp.position);

fprintf(fp,"%d%s%s%d%s%s\n",emp.id,,emp.gender,emp.age,emp.department,emp.position);fclose(fp);printf("職工信息錄入成功\n");}```3.職工信息查詢模塊：根據用戶輸入的查詢條件，在數組或文件中查找相應的職工信息并顯示。```cvoidsearchEmployee(){intid,found=0;Employeeemp;FILE*fp;fp=fopen("employees.txt","r");if(fp==NULL){printf("文件打開失敗\n");return;}printf("請輸入要查詢的職工編號:");scanf("%d",&id);

while(fscanf(fp,"%d%s%s%d%s%s",&emp.id,,emp.gender,&emp.age,emp.department,emp.position)!=EOF){if(emp.id==id){printf("職工編號:%d\n",emp.id);printf("職工姓名:%s\n",);printf("職工性別:%s\n",emp.gender);printf("職工年齡:%d\n",emp.age);printf("職工部門:%s\n",emp.department);printf("職工職位:%s\n",emp.position);found=1;break;}}if(!found){printf("未找到該職工信息\n");}fclose(fp);}```4.職工信息修改模塊：根據用戶輸入的職工編號，查找并修改相應職工的信息。```cvoidupdateEmployee(){intid,found=0;Employeeemp;FILE*fp,*temp;fp=fopen("employees.txt","r");temp=fopen("temp.txt","w");if(fp==NULL||temp==NULL){printf("文件打開失敗\n");return;}printf("請輸入要修改的職工編號:");scanf("%d",&id);

while(fscanf(fp,"%d%s%s%d%s%s",&emp.id,,emp.gender,&emp.age,emp.department,emp.position)!=EOF){if(emp.id==id){printf("請輸入新的職工姓名:");scanf("%s",);printf("請輸入新的職工性別:");scanf("%s",emp.gender);printf("請輸入新的職工年齡:");scanf("%d",&emp.age);printf("請輸入新的職工部門:");scanf("%s",emp.department);printf("請輸入新的職工職位:");scanf("%s",emp.position);found=1;}fprintf(temp,"%d%s%s%d%s%s\n",emp.id,,emp.gender,emp.age,emp.department,emp.position);}fclose(fp);fclose(temp);if(!found){printf("未找到該職工信息\n");remove("temp.txt");}else{remove("employees.txt");rename("temp.txt","employees.txt");printf("職工信息修改成功\n");}}```5.職工信息刪除模塊：根據用戶輸入的職工編號，在數組或文件中刪除相應的職工信息。```cvoiddeleteEmployee(){intid,found=0;Employeeemp;FILE*fp,*temp;fp=fopen("employees.txt","r");temp=fopen("temp.txt","w");if(fp==NULL||temp==NULL){printf("文件打開失敗\n");return;}printf("請輸入要刪除的職工編號:");scanf("%d",&id);

while(fscanf(fp,"%d%s%s%d%s%s",&emp.id,,emp.gender,&emp.age,emp.department,emp.position)!=EOF){if(emp.id!=id){fprintf(temp,"%d%s%s%d%s%s\n",emp.id,,emp.gender,emp.age,emp.department,emp.position);}else{found=1;}}fclose(fp);fclose(temp);if(!found){printf("未找到該職工信息\n");remove("temp.txt");}else{remove("employees.txt");rename("temp.txt","employees.txt");printf("職工信息刪除成功\n");}}```6.考勤記錄管理模塊：可以錄入考勤記錄，統計出勤天數、請假天數、曠工天數等。```cvoidattendanceManagement(){Attendanceatt;FILE*fp;intdaysWorked=0,daysAbsent=0,daysLeave=0;chardate[10];charstatus[10];

fp=fopen("attendance.txt","a");if(fp==NULL){printf("文件打開失敗\n");return;}printf("請輸入職工編號:");scanf("%d",&att.id);printf("請輸入日期(格式:YYYY-MM-DD):");scanf("%s",date);printf("請輸入考勤狀態(出勤、請假、曠工):");scanf("%s",status);

strcpy(att.date,date);strcpy(att.status,status);fprintf(fp,"%d%s%s\n",att.id,att.date,att.status);

if(strcmp(status,"出勤")==0){daysWorked++;}elseif(strcmp(status,"請假")==0){daysLeave++;}elseif(strcmp(status,"曠工")==0){daysAbsent++;}fclose(fp);

printf("考勤記錄錄入成功\n");printf("出勤天數:%d\n",daysWorked);printf("請假天數:%d\n",daysLeave);printf("曠工天數:%d\n",daysAbsent);}```7.工資信息管理模塊：可以錄入工資信息，計算總工資，并進行工資信息的查詢和修改。```cvoidsalaryManagement(){Salarysal;FILE*fp;intchoice;do{printf("\n工資信息管理\n");printf("1.錄入工資信息\n");printf("2.查詢工資信息\n");printf("3.修改工資信息\n");printf("0.返回主菜單\n");printf("請選擇:");scanf("%d",&choice);

switch(choice){case1:addSalary();break;case2:searchSalary();break;case3:updateSalary();break;case0:break;default:printf("無效選擇，請重新輸入\n");}}while(choice!=0);}

voidaddSalary(){Salarysal;FILE*fp;fp=fopen("salary.txt","a");if(fp==NULL){printf("文件打開失敗\n");return;}printf("請輸入職工編號:");scanf("%d",&sal.id);printf("請輸入基本工資:");scanf("%f",&sal.basicSalary);printf("請輸入績效工資:");scanf("%f",&sal.performanceSalary);printf("請輸入獎金:");scanf("%f",&sal.bonus);sal.totalSalary=sal.basicSalary+sal.performanceSalary+sal.bonus;

fprintf(fp,"%d%.2f%.2f%.2f%.2f\n",sal.id,sal.basicSalary,sal.performanceSalary,sal.bonus,sal.totalSalary);fclose(fp);printf("工資信息錄入成功\n");}

voidsearchSalary(){intid,found=0;Salarysal;FILE*fp;fp=fopen("salary.txt","r");if(fp==NULL){printf("文件打開失敗\n");return;}printf("請輸入要查詢的職工編號:");scanf("%d",&id);

while(fscanf(fp,"%d%f%f%f%f",&sal.id,&sal.basicSalary,&sal.performanceSalary,&sal.bonus,&sal.totalSalary)!=EOF){if(sal.id==id){printf("職工編號:%d\n",sal.id);printf("基本工資:%.2f\n",sal.basicSalary);printf("績效工資:%.2f\n",sal.performanceSalary);printf("獎金:%.2f\n",sal.bonus);printf("總工資:%.2f\n",sal.totalSalary);found=1;break;}}if(!found){printf("未找到該職工工資信息\n");}fclose(fp);}

voidupdateSalary(){intid,found=0;Salarysal;FILE*fp,*temp;fp=fopen("salary.txt","r");temp=fopen("temp.txt","w");if(fp==NULL||temp==NULL){printf("文件打開失敗\n");return;}printf("請輸入要修改的職工編號:");scanf("%d",&id);

while(fscanf(fp,"%d%f%f%f%f",&sal.id,&sal.basicSalary,&sal.performanceSalary,&sal.bonus,&sal.totalSalary)!=EOF){if(sal.id==id){printf("請輸入新的基本工資:");scanf("%f",&sal.basicSalary);printf("請輸入新的績效工資:");scanf("%f",&sal.performanceSalary);printf("請輸入新的獎金:");scanf("%f",&sal.bonus);sal.totalSalary=sal.basicSalary+sal.performanceSalary+sal.bonus;found=1;}fprintf(temp,"%d%.2f%.2f%.2f%.2f\n",sal.id,sal.basicSalary,sal.performanceSalary,sal.bonus,sal.totalSalary);}fclose(fp);fclose(temp);if(!found){printf("未找到該職工工資信息\n");remove("temp.txt");}else{remove("salary.txt");rename("temp.txt","salary.txt");printf("工資信息修改成功\n");}}```

文件操作設計系統將職工信息存儲在`employees.txt`文件中，考勤記錄存儲在`attendance.txt`文件中，工資信息存儲在`salary.txt`
