今天写了一个这样的代码：

#include<bits/stdc++.h>
using namespace std;
typedef long long int ll;
const int MX=1e6+10;
const int mod=1e9+7;
int main(){
	freopen("main.txt","w",stdout);
	cout << 114514;
	fclose(stdout);
	cout << 1919810;
	freopen("main.txt","r",stdin);
	int a;
	cin >> a;
	if(a==114514){
		cout << 114514;
	}
	return 0;
}

然后运行的时候被火绒卡掉了，火绒是这么说的：

请问有没有神犇解释一下为什么
