为什么结果是这样的#include <iostream>

Question

为什么结果是这样的，按着我的代码该怎么改，哪里有错

#include<iostream>
using namespace std;
struct stu
{
    int xh;
    char name[20];
    int c[3];
};
struct stu d[100];
int main()
{
    int n,i,j;
    cin>>n;
    for(i=0;i<n;i++)
    {
        cin>>d[i].xh>>d[i].name;
        for(j=0;j<3;j++)
        {
            cin>>d[i].c[j];
        }
    }
    int t=0,e=0;
    for(i=1;i<+n;i++)
    {    
        int sum=0;    
        for(j=0;j<3;j++)
        {
            
            sum=d[i].c[j]+sum;
        }
        if(sum>t)
        {
            t=sum;
            e++;
        }
    }
    for(i=0;i<n;i++)
    {
        if(i==e)
        {
            cout<<d[i].xh<<" "<<d[i].name<<" ";
            for(j=0;j<3;j++)
            {
                cout<<d[i].c[j]<<" ";
            }
        }
    }
    return 0;
}

给你写一个吧

#include <bits/stdc++.h>

using namespace std;

struct Student {
    string id;
    string name;
    int grade[3];
    int sum;
};

int n;
vector<Student> stu;

int main() {
    cin >> n;
    stu.resize(n);
    for (int i = 0; i < n; i++) {
        cin >> stu[i].id >> stu[i].name;
        stu[i].sum = 0;
        for (int j = 0; j < 3; j++) {
            cin >> stu[i].grade[j];
            stu[i].sum += stu[i].grade[j];
        }
    }

    int max_sum = -1, max_idx = -1;
    for (int i = 0; i < n; i++) {
        if (stu[i].sum > max_sum) {
            max_sum = stu[i].sum;
            max_idx = i;
        }
    }

    cout << stu[max_idx].id << " " << stu[max_idx].name << " " << stu[max_idx].grade[0] << " " << stu[max_idx].grade[1] << " " << stu[max_idx].grade[2] << endl;

    return 0;
}
