C小型企业工资管理系统

1、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

2、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 print

3、total(cout<<""< cout<<"Total "< "< cout<<""< 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(cout<<""< "< "< "< cout<<""< cout

4、<<""< "< "< "< cout<<""< cout<<""< "< "< "< cout<<""< cout<<""< "< "< "< void print(cout<<""< cout<<"&q

5、uot;< "< "< " < "< "< 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(!outfilecout<<"f can't open.n"abort(;outfile<<"Sales manger"< outfile<&

6、lt;"ID"< 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 #include class employeepublic:employee(salary=0;void pay(void print(void input(cout<<"ID:"cin>>no;cout<<" NAME:"cin>>name;cout<<" SEX(m/w:"ci
