C++-struct类的新特性当class用

 #include <iostream>
 #include <iomanip>
 #include <string>

 using namespace std;

 struct Student
 {
     int num;
     string name;
     char sex;
     int age;
     Student(int newnum,string newname,char newsex,int newage):num(newnum),name(newname),sex(newsex),age(age)
     {
         cout<<"Num: "<<num<<endl;
         cout<<"Name: "<<name<<endl;
         cout<<"Sex: "<<sex<<endl;
         cout<<"Age: "<<age<<endl;
     }
 };

 int main()
 {
     Student stu(,"Lin Lin",'F',);

     return ;
