C++小型企业工资管理系统.doc

一、需求分析1. 从要求上来看是要对各个员工的各种情况(名字、年龄、性别、职位、工资状况)进行输入。然后可以输出.2. 可以对于员工数据进行修改,可以查询.3. 对于员工的各种情况系统还可以进行统计排名.二、概要设计首先,创建了一个employee类.然后派生出四个类: manager、technician、salesman、sales manager.在派生类中定义了三个构造函数,分别是:数据输入函数(Input),表格输出函数(Print),排序函数(Pay).其次,在总体结构上,建立以各根菜单,用于选择各种功能.1. Input(数据输入):输入员工的各种数据.2. Total(数据统计):将员工的总数据进行对比排序,然后输出.3. Output(数据显示):显示输入的各种数据.4. Save(数据保存):对输入的数据进行保存备份.5. Eixt(退出程序):执行退出程序命令.三、详细设计1. Input(数据输入): 定义了各个岗位的人员的类，并把每个类的人员的属性设为类中的保护成员，其中技术工的工作时间和每小时的所得为私有成员，而销售员的销售额、经理的工资和销售经理的所辖部门的销售额和其底薪设为公有成员，再依次录入。2. Total(数据统计): 根据所有类的工资算法在其所属类中定义一个函数void pay()来根据各个职位的具体情况来计算工资，并且算出的工资经过冒泡法排序.void printtotal()coutendl;coutTotal setw(10)total endl;coutendl;3. Output(数据显示): 通过do-while循环以及制表格和setw的使用将输入的数据和统计并排序的数据以表格的形式打印出来，销售额合计一栏宽度要大些。void saleprint()coutsetw(10)no1setw(10)name1setw(10)sale1endl;coutendl;coutsetw(10)no2setw(10)name2setw(10)sale2endl;coutendl;coutsetw(10)no3setw(10)name3setw(10)sale3endl;coutendl;coutsetw(10)no4setw(10)name4setw(10)sale4endl;void print()coutendl;coutsetw(10)nosetw(10)namesetw(10)sexsetw(10)agesetw(10)salaryendl;4. Save(数据保存): 通过函数save()来将输入的数据和统计并排序的数据进行保存.例如:void save()fstream outfile;outfile.open(f:flsdfj.txt,ios:app);if(!outfile)coutf cant open.n;abort();outfileSales mangerendl;outfileIDnoNAMEnameSEXsexAGEageSALARYsalaryendl; 5. Eixt(退出):利用exit来完成退出系统功能。四、设计和调试分析程序清单:#include#include#include#include#includeclass employeepublic:employee()salary=0;void pay()void print()void input()coutno;coutname;coutsex;coutage;protected:int no;char name8;float salary;char sex;int age;class manager:virtual public employeeprotected:float monthlypay,sale;public:manager()monthlypay=8000; void input()coutManger;employee:input();void save()fstream outfile;outfile.open(f:flsdfj.txt,ios:app);if(!outfile)coutf cant open.n;abort();outfileMangerendl;outfileIDnoNAMEnameSEXsexAGEageSALARYsalaryendl;void pay()salary=monthlypay;void print()coutendl;coutsetw(10)nosetw(10)namesetw(10)sexsetw(10)agesetw(10)salaryendl;class technician:virtual public employeeprivate:float hourlyrate;int workhours;public:technician()hourlyrate=100;void pay()coutnameworkhours;salary=hourlyrate*workhours;void input()coutTECHNICIANendl;employee:input();void save()fstream outfile;outfile.open(f:flsdfj.txt,ios:app);if(!outfile)coutf cant open.n;abort();outfileTECHNICIANendl;outfileIDnoNAMEnameSEXsexAGEageSALARYsalaryendl;void print()coutendl;coutsetw(10)nosetw(10)namesetw(10)sexsetw(10)agesetw(10)salaryendl;class salesman:virtual public employeeprotected:float commrate;float sales;public:salesman()commrate=0.04; void input()coutSALEMAN;employee:input();void save()fstream outfile;outfile.open(f:flsdfj.txt,ios:app);if(!outfile)coutf cant open.n;abort();outfileTECHNICIANendl;outfileIDnoNAMEnameSEXsexAGEageSALARYsalaryendl;void pay()coutnamesales; salary=sales*commrate;void print()coutendl;coutsetw(10)nosetw(10)namesetw(10)sexsetw(10)agesetw(10)salaryendl;class salesmanager:virtual public manager,virtual public salesmanprivate:float total;int no1,no2,no3,no4;char name18,name28,name38,name48;float sale1,sale2,sale3,sale4;public:void salemanager()monthlypay=5000;commrate=0.005;void input()coutSales manger;employee:input();void save()fstream outfile;outfile.open(f:flsdfj.txt,ios:app);if(!outfile)coutf cant open.n;abort();outfileSales mangerendl;outfileIDnoNAMEnameSEXsexAGEageSALARYsalaryendl;void savesale()fstream outfile;outfile.open(f:flsdfj.txt,ios:app);if(!outfile)coutf cant open.n;abort();outfileThe salary of saleman of sales manger and themselvesendl;outfileIDno1NAMEname1SALARYsale1endl;outfileIDno2NAMEname2SALARYsale2endl;outfileIDno3NAMEname3SALARYsale3endl;outfileIDno4NAMEname4SALARYsale4endl;void pay()coutnameThe sales volume of everydepartment:;salary=monthlypay+commrate*total;float totalsale()total=sale1+sale2+sale3+sale4;return total;void printtotal()coutendl;coutTotal setw(10)total endl;coutendl;void sort(salesmanager p)int tmp,i,j;for(j=0;j2;j+)for(i=0;i2;i+)if(totalp.salary)tmp=salary;total=p.salary;p.salary=tmp;tmp=no;no=p.no;p.no=tmp;void saler()coutno1;coutname1;coutsale1;coutno2;coutname2;coutsale2;coutno3;coutname3;coutsale3;coutno4;coutname4;coutsale4;void saleprint()coutsetw(10)no1setw(10)name1setw(10)sale1endl;coutendl;coutsetw(10)no2setw(10)name2setw(10)sale2endl;coutendl;coutsetw(10)no3setw(10)name3setw(10)sale3endl;coutendl;coutsetw(10)no4setw(10)name4setw(10)sale4endl;void print()coutendl;coutsetw(10)nosetw(10)namesetw(10)sexsetw(10)agesetw(10)salaryendl;void main()manager m4;technician t4; salesman s4;salesmanager sm4;t1.save();int flag=1,operate; do cout # The system of salary manger #n; cout n; cout Chose your actions n; cout Input：1，Enter n; cout Total：2，Enter n; cout Output：3，Enter n; cout Save：4，Enter n; cout Exit：5，Enter n; cout n; coutoperate;switch(operate)case 1:coutWaiting for a minute!endl;for(int i=0;i4;i+)mi.input();for(int j=0;j4;j+)tj.input();for(int k=0;k4;k+)sk.input();for(int l=0;l4;l+)sml.input();for(int i=0;i4;i+)mi.pay();for(int j=0;j4;j+)tj.pay();for(int k=0;k4;k+)sk.pay();for(int l=0;l4;l+)sml.pay();sml.saler();break;case 2:coutWaiting for a minute!endl; for(int l=0;l4;l+)sml.totalsale();for(int i=0;i4;i+)for(int j=0;j2;j+)smj.sort(smj+1);coutThe saleman of the first sales mangerendl;coutendl;coutID NAME SALARY endl;sm0.saleprint();sm0.printtotal();cout The order is completeendl;coutList names of every sales mangerendl;coutendl;coutID NAME SEX AGE SALARY endl;for(int k=0;k4;k+)smk.print();coutendl;break;case 3:coutWaiting for a minute!endl;cout The blank of the ：endl;coutendl;coutID NAME SEX AGE SALARY endl;for(int i=0;i4;i+)mi.print();coutendl;coutendl;coutendl;coutendl;coutID NAME SEX AGE SALARY endl;for(int k=0;k4;k+)sk.print();coutendl;coutendl;coutendl;break;case 4:coutWaiting for a minute!endl;for(int i=0;i4;i+)mi.save();for(int j=0;j4;j+)tj.save();for(int k=0;k4;k+)sk.save();for(int l=0;l4;l+)sml.save();cout Informatio
