实验任务三源码如下：1#pragmaonce2#include<iostream>3#include<string>4usingstd::string;5usingstd::cout;6usingstd::endl;7classMachinePets{8private:9stringnickname;10public:11MachinePets(conststring

任务3源码：1#pragmaonce23#include<iostream>4#include<string>56usingstd::string;789classMachinePets{10public:11MachinePets(conststring&s);1213public:14virtualstringget_nickname

任务一、 任务二、 2【通过sort库函数来实现，其中，写了一个比较函数来作为sort的参数】 3【通过ChatGPT】 3、任务三、 1#pragmaonce2#include<string>3usingnamespacestd;45classMachinePets{6private:7stringnickname;8pub
