銷售公司人員管理

1、 C+大作業(yè)報告 班級：031013 學號：姓名：銷售公司員工管理一題目：設計一個虛基類Staff（員工），包含編號、姓名和年齡保護數(shù)據(jù)成員以及相關的成員函數(shù)；由Staff派生出銷售員類Salesman，包含銷售額保護數(shù)據(jù)成員以及相關的成員函數(shù)；再由Staff派生出經(jīng)理類Manager；然后由Salesman和Manager類派生出銷售經(jīng)理類SalesManager。設計一個利用文件處理方式實現(xiàn)對公司人員（包括銷售員、經(jīng)理和銷售經(jīng)理）進行管理，具有增加數(shù)據(jù)、更新數(shù)據(jù)、查詢數(shù)據(jù)、刪除數(shù)據(jù)以及重組文件的功能。（刪除數(shù)據(jù)在記錄中做刪除標志，重組文件指在物理上刪除有刪除標志的記錄。）另外要求分別統(tǒng)計這

2、三類員工的人數(shù)以及所有員工的總數(shù)。二 分析，流程及編程思想：首先定義一個虛基類Staff類，然后通過虛擬繼承生成Salesman類和Manager類，最后由Salesman和Manager派生出銷售經(jīng)理類SalesManager。這四個類中定義InputFromFile(istream &in)這一輸入函數(shù)，另外每個類還定義輸入信息和輸出信息的成員函數(shù),之后定義StaffChart、SalesmanChart、ManagerChart和SalesManagerChart四個類來，為實現(xiàn)增加、更新、查詢、刪除以及特定類別人員顯示，特定類別人員數(shù)目顯示的功能定義addItem、modify

3、Item、find、removeItem以及display、findnumber函數(shù)。最后在主函數(shù)定義Staff_Chart、Salesman_Chart、Manager_Chart和SalesManager_Chart四個對象，通過循環(huán)執(zhí)行并用switch函數(shù)選擇功能，然后調(diào)用相關的函數(shù)來實現(xiàn)各種功能。三 實驗代碼：#include"iostream"#include"fstream"using namespace std;class Staff protected:char num10;char name10;int age;public:Staff
