C++小型企業(yè)工資管理系統(tǒng)

1、1. 一、需求分析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）進行輸入。然后可以輸出.2. 可以對于員工數(shù)據(jù)進行修改，可以查詢.3. 對于員工的各種情況系統(tǒng)還可以進行統(tǒng)計排名.二、概要設(shè)計首先，創(chuàng)建了一個employee類.然后派生出四個類：manager、technician、salesman、salesmanager.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）：將

2、員工的總數(shù)據(jù)進行對比排序，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)進行保存?zhèn)浞?5. Eixt（退出程序）：執(zhí)行退出程序命令.1. 三、詳細設(shè)計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屆性設(shè)為類中的保護成員，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):根據(jù)所有類的工資算法在其所屆類中定義一個函數(shù)voidpay()來根據(jù)各個職位的具體情況來計算工資，并且算出的工資經(jīng)過冒泡法排序.void

3、printtotal()(cout<<""<<endl;cout<<"Total"<<setw(10)<<total<<""<<endl;cout<<""<<endl;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)計并排序的數(shù)據(jù)以表格的形式打印出來，銷售額合計一欄寬度要大些。voidsaleprint()(cout<<"|"<

8、輸入的數(shù)據(jù)和統(tǒng)計并排序的數(shù)據(jù)進行保存.例如：voidsave()fstreamoutfile;outfile.open("f:flsdfj.txt",ios:app);if(!outfile)cout<<"fcan'topen.n"abort();outfile<<"Salesmanger"<<endl;outfile<<"ID"<<no<<"NAME"<<name<<"SEX&qu

9、ot;<<sex<<"AGE"<<age<<"SALARY"<<salary<<endl;4. Eixt(退出):利用exit來完成退出系統(tǒng)功能。四、設(shè)計和調(diào)試分析程序活單：#include<iostream.h>#include<stdlib.h>#include<fstream.h>#include<iomanip.h>#include<string.h>classemployeepublic：employee()sal
