C++实现职工信息管理系统

本文实例为大家分享了c++实现职工信息管理系统的具体代码，供大家参考，具体内容如下
1、项目需求
2、功能实现的具体思路为:
(1) 经行职工信息的读入，用while循环进行读入，对于职工信息类型的设定方便起见除年龄和薪资用int类型其他信息都用string类型，职工信息用ostream 流写入txt并将信息保存在txt文件中，打印职工信息由于c++读文件方式不方便所以用c语言方式读文件，文件读取以后将文件中读取的信息加载到vector容器中后打印在终端窗口，其他功能的实现也是将文件中的信息读取到vector容器中，后用vector容器中的重载函数进行功能的实现；
3、头文件的编写的具体实现
#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();
//职工信息描述
string description();
//录入职工信息
static void addWorkerInformation(vector<Worker>&worker);
void addWorkerInformations();
//职工信息浏览
void putWorkerInformation();
//查询 按籍贯或学历查询职工信息
void lookWorkerInformation();
//按工资高低排序
void sortWorkerInformation();
//删除职工信息 按姓名删除
void deleteWorkerInformation();
//修改职工信息 把研究生薪资增加 500
void addWorkerSalary();
friend ostream& operator<<(ostream& os, const Worker& worker); //友元函数直接输出对象的信息
Worker& operator=(const Worker& worker); //赋值构造函数
private:
string workNumber; //职工号
string name; //名字
string gender; //性别
string education; //学历
string addr; //籍贯
string phoneNumber; //电话号码
int age; //年龄
int salary; //薪资
void loadWorkerInformation();
void printWorkerInformation();
vector<Worker>worker;
};
ostream& operator<<(ostream& os, const Worker& worker); //使用重载函数直接输出对象的信息进行输出
4、对头文件中函数的具体实现
#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(){
}
//职工信息描述
string Worker::description(){
stringstream ret;
ret << "职工号:" << workNumber << " 性别:" << gender << " 名字:" << name
<< " 年龄:" << age << " 学历:" << education << " 籍贯:" << addr
<< " 薪资:" << salary << " 电话号码:" << phoneNumber;
return ret.str();
}
void Worker::addWorkerInformation(vector<Worker>& worker){
string workNumber; //职工号
string name; //名字
string gender; //性别
string education; //学历
string addr; //籍贯
string phoneNumber; //电话号码
int age; //年龄
int salary; //年龄
while (1) {
cout << "输入职工号[输入 0 结束输入];";
cin >> workNumber;
if (workNumber == ZERO) {
break;
}
cout << "输入名字:";
cin >> name;
cout << "输入性别:";
cin >> gender;
cout << "输入学历:";
cin >> education;
cout << "输入籍贯:";
cin >> addr;
cout << "输入电话号码:";
cin >> phoneNumber;
cout << "输入年龄:";
cin >> age;
cout << "输入薪资:";
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();
}
//职工信息浏览
void Worker::putWorkerInformation(){
loadWorkerInformation();
printWorkerInformation();
}
//查询 按籍贯或学历查询职工信息
void Worker::lookWorkerInformation(){
string addr;
string education;
cout << "输入要查询的职工籍贯:";
cin >> addr;
cout << "请输入要查询的职工学历:";
cin >> education;
loadWorkerInformation();
for (int i = 0;i < worker.size();i++) {
if ((worker[i].addr == addr)&&(worker[i].education == education)){
cout << worker[i] << endl;
}
}
}
//按工资高低排序
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();
}
//删除职工信息 按姓名删除
void Worker::deleteWorkerInformation(){
ofstream outFile;
string name;
cout << "请输入你要删除人的姓名:";
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++;
}
}
}
//修改职工信息 把研究生薪资增加 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]; //职工号
char name[32]; //名字
char gender[32]; //性别
char education[32]; //学历
char addr[32]; //籍贯
char phoneNumber[32]; //电话号码
int age; //年龄
int salary; //年龄
string line;
ifstream inFile;
inFile.open(NAME);
if (!inFile.is_open()) {
cout << "----职工数据库打开失败----";
inFile.close();
exit(1);
}
while (1) {
getline(inFile, line);
if (inFile.eof()) {
break;
}
if (line == "")continue;
sscanf_s(line.c_str(), "职工号:%s 性别:%s 名字:%s 年龄:%d 学历:%s 籍贯:%s 薪资:%d 电话号码:%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<< "职工号:" <<worker.workNumber << " 性别:" << worker.gender << " 名字:" << worker.name
<< " 年龄:" << worker.age << " 学历:" << worker.education << " 籍贯:" << worker.addr
<< " 薪资:" << worker.salary << " 电话号码:" << worker.phoneNumber;
return os;
}
5、main函数的具体实现
#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 << "输入【1】根据籍贯和学历对职工信息进行查询" << endl;
cout << "输入【2】按薪水对职工信息进行排序" << endl;
cout << "输入【3】打印职工信息" << endl;
cout << "输入【4】增加职工信息" << endl;
cout << "输入【5】增加研究生薪水" << endl;
cout << "输入【6】删除信息" << endl;
cout << "输入【7】退出功能" << endl << endl;
bool quit = false;
do {
if (_kbhit()) {
char ch = _getch();
switch(ch){
case ONE:
work.lookWorkerInformation();//根据籍贯和学历对职工信息进行查询
cout << "---已完成该功能---" << endl << endl;
break;
case TWO:
work.sortWorkerInformation();//按薪水对职工信息进行排序
cout << "---已完成该功能---" << endl << endl;
break;
case THREE:
work.putWorkerInformation();//打印职工信息;
cout << "---已完成该功能---" << endl << endl;
break;
case FOUR:
work.addWorkerInformations();//增加职工信息
cout << "---已完成该功能---" << endl << endl;
break;
case FIVE:
work.addWorkerSalary();//增加研究生薪水
cout << "---已完成该功能---" << endl << endl;
break;
case SIX:
work.deleteWorkerInformation();//删除信息
cout << "---已完成该功能---" << endl << endl;
break;
case SEVEN:
quit = true;//退出循环
break;
default:
cout << "----无其他功能选项----";
break;
}
}
} while (quit == false);
system("pause");
return 0;
}
6、功能3，4，5，6，的实现都是将文件中的信息加载到vector中，并且使用的都是保存了worker这个类对象的同一个容器（假如先实现工能3，将信息加载到vector中后功能3结束以后，功能3使用到的职工信息依然在vector这个容器中，所以使用完一个函数后要将vector中的信息清理完全，不然会影响下一个函数的使用）。
7、在实现功能5的时候会使用到vector容器的重载函数（ worker.erase(worker.begin()+i);）使用完以后返回的是下一个迭代器指向下一个对象，所以在使用使用for循环遍历容器的时候因注意for (int i = 0;i < worker.size();i++) 中i++具体放在哪个位置比较合适。
8、这是本人在编写程序的时候发现的坑如果有什么错误请批评指正。
