엔터티 클래스 도구를 사용하여 C++에서 Java 구현 생성

前言

原因是这样的，eclipse有那种生成实体类的插件，可是我感觉装来装去很麻烦，于是我想，干脆自己做一个生成实体类的工具吧，说做就做，然后就自己花了两个小时左右做出来了一个，以后应该能大大提高工作效率吧。

实现方法

输入：属性个数
输入：type virableName
输出：d盘下面的example文件，该文件里面生成了实体类的代码

原理就是填充数据而已。。。根本没有难度
然后用了map模板把数据存起来了

使用截图

**这个是数据截图，CKCommand表示类，5表示有几个属性，剩下的都是数据属性
然后把这个数据复制进控制台运行就可以了**

运行截图

最后的实体类截图

注意去D盘下面找

代码

#include  <iostream>
#include  <string>
#include <map>
#include <fstream>
using namespace std;
int main()
{    
      int num;  //总体的成员个数
    string  which1, Vname,classname;    
    map<string, string > mapStudent;    //这个我服了
    map <string, string >::iterator m1_Iter;    
    cin >> classname;    
    cin >> num;    
    for (int i = 0; i<num; i++){        
    cin >> which1 >> Vname;

        mapStudent[Vname] = which1;

    }    
    
    cout << "Congratulation that you are success!"<<endl;

    ofstream examplefile("d:\\example.txt");
