Problem FCTRL2 - Small factorials

Where is bug? (C++)

#include <iostream>

using namespace std;
int main()
{
	int howMuch, x;
	long double result;
	cin >> howMuch;
	for (int i = 0; i < howMuch; i++)
	{
		cin >> x;
		result = 1;
		for (int j = 1; j <= x; j++)
		{
			result *= j;
		}
		cout << result << endl;
	}

    return 0;
}
