求助，哪里错了

#include <bits/stdc++.h>
using namespace std;

string mnc[1510000],okmnc;int geshu[500000],jl[100000000];
int main(){
	int i = 1;
	long long he,minhe = 3e9;
	while(cin >> geshu[i] >> jl[i] >> mnc[i]){
		i++;
	}
	for (int j = 1;j <= i;j++){
		he = 0;
		for (int k = 1;k <= i;k++)
			he += abs(jl[j] * geshu[j] - jl[k] * geshu[k]);
		if (he < minhe){
			minhe = he;
			okmnc = mnc[j];
		}
	}
	cout << okmnc << " " << minhe;
}
