@Lying_Flat666 求关注～

#include <iostream>
#include <algorithm>
using namespace std;
struct Person

    int id, chi, math, eng, sum;
    void read()
    {
        cin >> chi >> math >> eng;
        sum = chi + math + eng;
    }
    void write()
    {
        cout << id << " " << sum << endl;
    }//要在结构体内定义一个输出数组
};
Person a[310];
bool cmp(Person x, Person y)
{
    if (x.sum != y.sum)
    {
        return x.sum > y.sum;
    }
    if (x.chi != y.chi)
    {
        return x.chi > y.chi;
    }
    return x.id < y.id;
}
int main()
{
    int n;
    cin >> n;
    for (int i = 1; i <= n; i++)
    {
        a[i].read();
        a[i].id = i;
    }
    sort(a + 1, a + n + 1, cmp);
    for (int i = 1; i <= 5; i++)

    }
    return 0;

@Lying_Flat666 num的顺序关系写反了
