第一个点过不了其他都过，求指教

#include<iostream>
#include<cmath>
using namespace std;
int main()
{
	int n;
	cin >> n;
	int arr[100];
	int input;
	int acount = 0;
	for (int i = 0; i < n; i++)
	{
		cin >> input;
		bool record = true;
		for (int j = 2; j <= sqrt(input); j++)
		{
			if (input % j == 0)
				record = false;
		}
		if (record)
		{
			arr[acount] = input;
			acount++;
		}
     }
	for (int i = 0; i < acount; i++)
	{
		cout << arr[i] << ' ';
	}
	return 0;
}
