A super classic C++ structure of the problem

Title description:
There are 10 students, and the data of each student includes the student number, name, English, math, and physics scores of three courses. Enter the data of 10 students from the keyboard, and ask to print out the total average scores of three courses, as well as the data of the students with the highest scores (including the student number, name, average scores of three courses and average scores).

C + + code:

#include<iostream>
#include<string>
using namespace std;
struct Student{//Declare the struct Student
 string num;
 string name;
 float english;
 float match;
 float physics;
 float average;
};
void shuchu(Student &s){//Structure content output function
 cout<<s.num<<"t";
 cout<<s.name<<"t";
 cout<<s.english<<"t";
 cout<<s.match<<"t";
 cout<<s.physics<<"t";
 cout<<s.average<<endl;
}
int main(){
 Student s[10];//Declares an array of structs
 cout<<"numtnametenglishtmatchtphysics"<<endl;
 int i=0;
 for(;i<10;i++){//Initialize the structure statistics
  cin>>s[i].num;
  cin>>s[i].name;
  cin>>s[i].english;
  cin>>s[i].match;
  cin>>s[i].physics;
  s[i].average=(s[i].english+s[i].match+s[i].physics)/3;  
 }
 float max=s[0].average;
 int k=1;
 cout<<"=============show data======="<<endl;
 for(i=0;i<10;i++){
             shuchu(s[i]);//Output the contents of the structure
      if(s[i].average>max){//The data with the highest average score was obtained by the ring method
      k=i;
      max=s[i].average;
     }
 }
 cout<<"The hightest:"<<endl;
 shuchu(s[k]);//Output the highest score data
 cout<<endl;
 return 0;
}
