using namespace std;

#include <iostream>
#include <string>
#include <list>
#include <iterator>

class person
{public:
string name;
string sex;
int age;

person::person(string a, string b, int c)
{name=a;
sex=b;
age=c;

};


int main()
{list<person>first;
first.push_back(person("liuxiang","male",28));
for(list<person>::const_iterator it=first.begin();it!=first.end();it++)
{cout<<endl<<*it<<endl;
}
system("pause");}

person(string a, string b, int c)//这个可以在类内声明，而在类外定义，那么要加类限定符；如果直接在类内定义就不用加类作用符
{name=a;
sex=b;
age=c;

}
friend ostream&operator<<(ostream &out,const person &rhs)//你要输出类，那么首先要定义成员函数
{
        out<<rhs.name<<"\t"<<rhs.sex<<"\t"<<rhs.age;
