使用C++实现在类中存储成员信息并存取

能够存储固定的一些姓名和信息，同时能够键入新成员，实现成员查找和全部输出。

#include <iostream>
using namespace std;

#define N  2         //新输入人数
#define pe_mum 6    //已有成员人数
class Works  //创建类
{
public:
    void input();//查找已有成员
    void output();//输出所有成员
    void task_init();//初始化已有成员
    void key_in()//输入新成员
    {
        int a = 0, s = 0;
        for (a = 0; a < N; a++)
        {
            s = a + 1;
            cout << "请输入第" << s << "个姓名" << endl;
            cin >> name[a];
            cout << "请输入任务" << endl;
            cin >> task[a];
        }
    }

    //新成员
    string name[N + 1];
    string task[N + 1];
    //已有成员
    string name2[pe_mum + 1];
    string task2[pe_mum + 1];
