這篇“C++怎么實現職工信息管理系統”除了程序員外大部分人都不太理解，今天小編為了讓大家更加理解“C++怎么實現職工信息管理系統”，給大家總結了以下內容，具有一定借鑒價值，內容詳細步驟清晰，細節處理妥當，希望大家通過這篇文章有所收獲，下面讓我們一起來看看具體內容吧。
具體內容如下
1、項目需求
2、功能實現的具體思路為:
(1) 經行職工信息的讀入，用while循環進行讀入，對于職工信息類型的設定方便起見除年齡和薪資用int類型其他信息都用string類型，職工信息用ostream 流寫入txt并將信息保存在txt文件中，打印職工信息由于c++讀文件方式不方便所以用c語言方式讀文件，文件讀取以后將文件中讀取的信息加載到vector容器中后打印在終端窗口，其他功能的實現也是將文件中的信息讀取到vector容器中，后用vector容器中的重載函數進行功能的實現；
3、頭文件的編寫的具體實現
#pragma once
#include<string>
#include<vector>
using namespace std;
class Worker {
public:
Worker(string workNumber, string name, string gender,
string education, string addr, string phoneNumber,
int age, int salary);
Worker();
~Worker();
//職工信息描述
string description();
//錄入職工信息
static void addWorkerInformation(vector<Worker>&worker);
void addWorkerInformations();
//職工信息瀏覽
void putWorkerInformation();
//查詢 按籍貫或學歷查詢職工信息
void lookWorkerInformation();
//按工資高低排序
void sortWorkerInformation();
//刪除職工信息 按姓名刪除
void deleteWorkerInformation();
//修改職工信息 把研究生薪資增加 500
void addWorkerSalary();
friend ostream& operator<<(ostream& os, const Worker& worker); //友元函數直接輸出對象的信息
Worker& operator=(const Worker& worker); //賦值構造函數
private:
string workNumber; //職工號
string name; //名字
string gender; //性別
string education; //學歷
string addr; //籍貫
string phoneNumber; //電話號碼
int age; //年齡
int salary; //薪資
void loadWorkerInformation();
void printWorkerInformation();
vector<Worker>worker;
};ostream& operator<<(ostream& os, const Worker& worker); //使用重載函數直接輸出對象的信息進行輸出
4、對頭文件中函數的具體實現
#include<string>
#include<sstream>
#include<iostream>
#include<fstream>
#include<vector>
#include"worker.h"
#define NAME "workerInformation.txt"
#define ZERO "0"
#define MONEY 500
#define STUDENT "研究生"
Worker::Worker(string workNumber, string name, string gender,
string education, string addr, string phoneNumber,
int age, int salary){
this->addr = addr;
this->age = age;
this->gender = gender;
this->name = name;
this->phoneNumber = phoneNumber;
this->education = education;
this->salary = salary;
this->workNumber = workNumber;
}
Worker::Worker(){
}
Worker::~Worker(){
}
//職工信息描述
string Worker::description(){
stringstream ret;
ret << "職工號:" << workNumber << " 性別:" << gender << " 名字:" << name
<< " 年齡:" << age << " 學歷:" << education << " 籍貫:" << addr
<< " 薪資:" << salary << " 電話號碼:" << phoneNumber;
return ret.str();
}
void Worker::addWorkerInformation(vector<Worker>& worker){
string workNumber; //職工號
string name; //名字
string gender; //性別
string education; //學歷
string addr; //籍貫
string phoneNumber; //電話號碼
int age; //年齡
int salary; //年齡
while (1) {
cout << "輸入職工號[輸入 0 結束輸入];";
cin >> workNumber;
if (workNumber == ZERO) {
break;
}
cout << "輸入名字:";
cin >> name;
cout << "輸入性別:";
cin >> gender;
cout << "輸入學歷:";
cin >> education;
cout << "輸入籍貫:";
cin >> addr;
cout << "輸入電話號碼:";

cout << "輸入薪資:";
cin >> salary;
worker.push_back(Worker(workNumber, name, gender,
education, addr, phoneNumber,
age, salary));
}
return;
}
void Worker::addWorkerInformations(){
ofstream outFile;
outFile.open(NAME,ios::app);
Worker::addWorkerInformation(this->worker);
for (int i = 0;i < worker.size();i++) {
outFile << worker[i].description()<<endl;
}
worker.clear();
outFile.close();
}
//職工信息瀏覽
void Worker::putWorkerInformation(){
loadWorkerInformation();
printWorkerInformation();
}
//查詢 按籍貫或學歷查詢職工信息
void Worker::lookWorkerInformation(){
string addr;
string education;
cout << "輸入要查詢的職工籍貫:";
cin >> addr;
cout << "請輸入要查詢的職工學歷:";
cin >> education;
loadWorkerInformation();
for (int i = 0;i < worker.size();i++) {
if ((worker[i].addr == addr)&&(worker[i].education == education)){
cout << worker[i] << endl;
}
}
}
//按工資高低排序
void Worker::sortWorkerInformation(){
loadWorkerInformation();
Worker workers;
for (int j = 0;j < worker.size() ;j++) {
for (int i = j + 1;i < worker.size();i++) {
if (worker[j].salary > worker[i].salary) {
workers = worker[i];
worker[i] = worker[j];
worker[j] = workers;
}
}
}
printWorkerInformation();
}
//刪除職工信息 按姓名刪除
void Worker::deleteWorkerInformation(){
ofstream outFile;
string name;
cout << "請輸入你要刪除人的姓名:";
cin >> name;
loadWorkerInformation();
outFile.open(NAME);
for (int i = 0;i < worker.size();) {
if (worker[i].name == name) {
worker.erase(worker.begin() + i);
}
else {
outFile << worker[i] << endl;
i++;
}
}
}
//修改職工信息 把研究生薪資增加 500
void Worker::addWorkerSalary(){
loadWorkerInformation();
int salary;
ofstream outFile;
outFile.open(NAME);
for (int i = 0;i < worker.size();) {
if (worker[i].education == STUDENT) {
salary = worker[i].salary + MONEY;
outFile<<Worker(worker[i].workNumber,worker[i].name,worker[i].gender,
worker[i].education, worker[i].addr, worker[i].phoneNumber,
worker[i].age, salary)<<endl;
worker.erase(worker.begin()+i);
}
else {
outFile << worker[i] << endl;
i++;
}
}
worker.clear();
}
Worker& Worker::operator=(const Worker& worker) {
addr = worker.addr;
age = worker.age;
gender = worker.gender;
education = worker.education;
name = worker.name;
phoneNumber = worker.phoneNumber;
salary = worker.salary;
workNumber = worker.workNumber;
return *this;
}
void Worker::loadWorkerInformation(){
char workNumber[32]; //職工號
char name[32]; //名字
char gender[32]; //性別
char education[32]; //學歷
char addr[32]; //籍貫
char phoneNumber[32]; //電話號碼
int age; //年齡
int salary; //年齡
string line;
ifstream inFile;
inFile.open(NAME);
if (!inFile.is_open()) {
cout << "----職工數據庫打開失敗----";
inFile.close();
exit(1);
}
while (1) {
getline(inFile, line);
if (inFile.eof()) {
break;
}
if (line == "")continue;
sscanf_s(line.c_str(), "職工號:%s 性別:%s 名字:%s 年齡:%d 學歷:%s 籍貫:%s 薪資:%d 電話號碼:%s",
workNumber, sizeof(workNumber), gender, sizeof(gender), name, sizeof(name),
&age, education, sizeof(education), addr, sizeof(addr), &salary,
phoneNumber, sizeof(phoneNumber));
worker.push_back(Worker(string(workNumber), string(name), string(gender),
string(education), string(addr), string(phoneNumber),
age, salary));
}
}
void Worker::printWorkerInformation(){
for (int i = 0;i < worker.size();i++) {
cout << worker[i] << endl<<endl;
}
worker.clear();
}
ostream& operator<<(ostream& os, const Worker& worker){
os<< "職工號:" <<worker.workNumber << " 性別:" << worker.gender << " 名字:" << worker.name
<< " 年齡:" << worker.age << " 學歷:" << worker.education << " 籍貫:" << worker.addr
<< " 薪資:" << worker.salary << " 電話號碼:" << worker.phoneNumber;
return os;
}5、main函數的具體實現
#include<stdlib.h>
#include<iostream>
#include<conio.h>
#include"worker.h"
#define ONE '1'
#define TWO '2'
#define THREE '3'
#define FOUR '4'
#define FIVE '5'
#define SIX '6'
#define SEVEN '7'
int main(void) {
Worker work;
cout << "輸入【1】根據籍貫和學歷對職工信息進行查詢" << endl;
cout << "輸入【2】按薪水對職工信息進行排序" << endl;
cout << "輸入【3】打印職工信息" << endl;
cout << "輸入【4】增加職工信息" << endl;
cout << "輸入【5】增加研究生薪水" << endl;
cout << "輸入【6】刪除信息" << endl;
cout << "輸入【7】退出功能" << endl << endl;
bool quit = false;
do {
if (_kbhit()) {
char ch = _getch();
switch(ch){
case ONE:
work.lookWorkerInformation();//根據籍貫和學歷對職工信息進行查詢
cout << "---已完成該功能---" << endl << endl;
break;
case TWO:
work.sortWorkerInformation();//按薪水對職工信息進行排序
cout << "---已完成該功能---" << endl << endl;
break;
case THREE:
work.putWorkerInformation();//打印職工信息;
cout << "---已完成該功能---" << endl << endl;
break;
case FOUR:
work.addWorkerInformations();//增加職工信息
cout << "---已完成該功能---" << endl << endl;
break;
case FIVE:
work.addWorkerSalary();//增加研究生薪水
cout << "---已完成該功能---" << endl << endl;
break;
case SIX:
work.deleteWorkerInformation();//刪除信息
cout << "---已完成該功能---" << endl << endl;
break;
case SEVEN:
quit = true;//退出循環
break;
default:
cout << "----無其他功能選項----";
break;
}
}
} while (quit == false);
system("pause");
return 0;
}6、功能3，4，5，6，的實現都是將文件中的信息加載到vector中，并且使用的都是保存了worker這個類對象的同一個容器（假如先實現工能3，將信息加載到vector中后功能3結束以后，功能3使用到的職工信息依然在vector這個容器中，所以使用完一個函數后要將vector中的信息清理完全，不然會影響下一個函數的使用）。
7、在實現功能5的時候會使用到vector容器的重載函數（ worker.erase(worker.begin()+i);）使用完以后返回的是下一個迭代器指向下一個對象，所以在使用使用for循環遍歷容器的時候因注意for (int i = 0;i < worker.size();i++) 中i++具體放在哪個位置比較合適。
8、這是本人在編寫程序的時候發現的坑如果有什么錯誤請批評指正。
