不知道哪里错了??????????????

#include<bits/stdc++.h>
using namespace std;
int n;
struct node{
    int x,y,z;
    int sum;
    int v;
}a[310];

    if(n1.sum==n2.sum){
        if(n1.x==n2.x){
            return n1.v<n2.v;
        }else{
            return n1.x>n2.x;
        }
    }else{
        return n1.sum>n2.sum;
    }
}
int main(){
    scanf("%d",&n);
    for(int i=1;i<=n;i++){
        scanf("%d &d %d",&a[i].x,&a[i].y,&a[i].z);
        a[i].v=i;
        a[i].sum=a[i].x+a[i].y+a[i].z;
    }
    sort(a+1,a+1+n,cmp);
    for(int i=1;i<=5;i++){
        cout<<a[i].v<<" "<<a[i].sum<<endl;
    }
    return 0;
}
