贴一下我的代码 你自己参考吧。

#include<cstdio>
#include<algorithm>
#include<vector>

using namespace std;

struct STUDENT {
    int yw;
    int tot;
    int xh;
} a[305];

bool cmp(struct STUDENT a, struct STUDENT b) {
    if (a.tot == b.tot) {
        if (a.yw == b.yw) {
            return a.xh < b.xh;
        }
        return a.yw > b.yw;
    }
    else {
        return a.tot > b.tot;
    }
}

int main(void) {
    int n, y, s, x;
    scanf("%d", &n);
    for (int i = 0; i < n; ++i) {
        scanf("%d%d%d", &y, &s, &x);
        a[i].yw = y; a[i].tot = y + s + x;
        a[i].xh = i;
    }
    sort(a, a+n, cmp);
    for (int i = 0; i < 5; ++i) {
        printf("%d %d\n", a[i].xh + 1, a[i].tot);
    }
    return 0;
}
