看上去没问题啊！！！

#include <bits/stdc++.h>
using namespace std;
int main() {
	int a[5], b[5], ans = 0;
	for (int i = 1; i <= 4; i++)cin >> a[i];
	for (int i = 1; i <= 4; i++)cin >> b[i];
	for (int i = 1; i <= 4; i++)for (int j = 1; j <= 4; j++)if (a[i] < b[j] && b[i] > a[j])ans++;
	cout << ans;
	return 0;
}
