设计一个结构体程序？

C程序设计：
最后的学生数据要求为学号、姓名、性别、年龄、语数外三门各科成绩，最后加一个按照从高到低输出学生三门各科成绩、总成绩列表的功能

#include<bits/stdc++.h>
using namespace std;
struct students{
    string id;
    string name;
    bool sex;
    int age;
    double Chinese,Math,English;
    double AllScore;
}stu[1000];
bool cmp1(students a,students b){return a.Chinese>b.Chinese;}
bool cmp2(students a,students b){return a.Math>b.Math;}
bool cmp3(students a,students b){return a.English>b.English;}
bool cmp4(students a,students b){return a.AllScore>b.AllScore;}
int main()
{
    int n;
    cin>>n;
    for(int i=0;i<n;i++)
        cin>>stu[i].id>>stu[i].name>>stu[i].sex>>stu[i].age>>stu[i].Chinese>>stu[i].Math>>stu[i].English,
        stu[i].AllScore=stu[i].Chinese+stu[i].Math+stu[i].English;
    
    cout<<"按语文成绩排序:"<<endl;
    sort(stu,stu+n,cmp1);
    for(int i=0;i<n;i++)
