C++小型企業(yè)工資管理系統(tǒng)

1、一、需求分析1. 從要求上來看是要對各個員工的各種情況(名字、年齡、性別、職位、工資狀況進(jìn)行輸入。然后可以輸出.2. 可以對于員工數(shù)據(jù)進(jìn)行修改,可以查詢.3. 對于員工的各種情況系統(tǒng)還可以進(jìn)行統(tǒng)計(jì)排名.二、概要設(shè)計(jì)首先,創(chuàng)建了一個employee類.然后派生出四個類: manager、technician、salesman、sales manager.在派生類中定義了三個構(gòu)造函數(shù),分別是:數(shù)據(jù)輸入函數(shù)(Input,表格輸出函數(shù)(Print,排序函數(shù)(Pay.其次,在總體結(jié)構(gòu)上,建立以各根菜單,用于選擇各種功能.1. Input(數(shù)據(jù)輸入:輸入員工的各種數(shù)據(jù).2. Total(數(shù)據(jù)統(tǒng)計(jì):將員工的

2、總數(shù)據(jù)進(jìn)行對比排序,然后輸出.3. Output(數(shù)據(jù)顯示:顯示輸入的各種數(shù)據(jù).4. Save(數(shù)據(jù)保存:對輸入的數(shù)據(jù)進(jìn)行保存?zhèn)浞?5. Eixt(退出程序:執(zhí)行退出程序命令.三、詳細(xì)設(shè)計(jì)1. Input(數(shù)據(jù)輸入: 定義了各個崗位的人員的類，并把每個類的人員的屬性設(shè)為類中的保護(hù)成員，其中技術(shù)工的工作時間和每小時的所得為私有成員，而銷售員的銷售額、經(jīng)理的工資和銷售經(jīng)理的所轄部門的銷售額和其底薪設(shè)為公有成員，再依次錄入。2. Total(數(shù)據(jù)統(tǒng)計(jì): 根據(jù)所有類的工資算法在其所屬類中定義一個函數(shù)void pay(來根據(jù)各個職位的具體情況來計(jì)算工資，并且算出的工資經(jīng)過冒泡法排序.void print

3、total(cout coutTotal cout 3. Output(數(shù)據(jù)顯示: 通過do-while循環(huán)以及制表格和setw的使用將輸入的數(shù)據(jù)和統(tǒng)計(jì)并排序的數(shù)據(jù)以表格的形式打印出來，銷售額合計(jì)一欄寬度要大些。void saleprint(cout cout cout cout cout cout cout void print(cout cout 4. Save(數(shù)據(jù)保存: 通過函數(shù)save(來將輸入的數(shù)據(jù)和統(tǒng)計(jì)并排序的數(shù)據(jù)進(jìn)行保存.例如:void save(fstream outfile;outfile.open(f:flsdfj.txt,ios:app;if(!outfilecoutf
