銷售公司人員管理

1、C+大作業(yè)報(bào)告班級： 031013學(xué)號：姓名：銷售公司員工管理一題目：設(shè)計(jì)一個(gè)虛基類 Staff (員工)，包含編號、姓名和年齡保護(hù)數(shù)據(jù)成員以及相關(guān)的成員函 數(shù)；由Staff派生出銷售員類 Salesman,包含銷售額保護(hù)數(shù)據(jù)成員以及相關(guān)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(shè)計(jì)一個(gè)利用文件處理方式實(shí)現(xiàn)對公司人員 (包括銷售員、 經(jīng)理和銷售經(jīng)理) 進(jìn)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(biāo)志,重組文件指在物理上刪除有刪除標(biāo)志的記錄。

2、)另外要求分別統(tǒng)計(jì)這三類員工 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(gè)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(gè)類中定義 InputFrom &n) 這一輸入函數(shù),另外每個(gè)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(gè)類來,為實(shí)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、

3、modifyItem 、 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(gè)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(guān)的函數(shù)來實(shí)現(xiàn)各種功能。三 實(shí)驗(yàn)代碼：#includeiostream #includefstream using namespace std;class Staffprotected:char num10;char name10;int age;public:Staff
