#include <bits/stdc++.h>
using namespace std;
void solve(){
	int n;
	cin >> n;
	cout << n;
}
int main(){
	printf("Count:");
	int n;
	scanf("%d", &n);
	for (int i = 1; i <= n; i++){
		char in[10001], out[10001];
		fclose(stdin);
		fclose(stdout);
		sprintf(in, "%d.in", i);
		sprintf(out, "%d.out", i);
		//freopen(in, "r", stdin);
		//freopen(out, "w", stdout);
		solve();
		fclose(stdin);
		fclose(stdout);
	}
	return 0;
}

为什么solve函数不运行？
