Factorial Code

[tcnjengineer]

I have to write a code that will calculate the factorial of an entered number and when the number is negative the program will exit the loop and display the message "Goodbye". I am having trouble getting the program to display the message and then properly exit the loop.

 #include <iostream>
using namespace std;

int main ()
{
	unsigned int n = 1;
	unsigned long long factorial = 1;
	int i = 0;

while (n>=0)
{
	cout << "Enter a positive integer (enter a negative number to quit) : ";
	cin >> n;

	if (n>0)
	{
		for (i=1; i <= n ; ++i)
		{
		factorial = factorial*i;
		}
		cout << "The factorial of " << n << " = " << factorial << endl;
		factorial = 1;
	}

	else
	{
		cout << "The factorial of 0 is 1." << endl;
	}

}

cout << "Goodbye!";

	return 0;
} Put the code you need help with here.

Thanks for the help

unsigned int n = 1;
while (n>=0)
{


That's not going to work too good :)
either stop if they enter zero (for example) or remove unsigned keyword.

If n is negative on line 15, the else will be triggered since n is not greater than 0. The simplest fix would be to make line 25 else if (n == 0).

currently n can't be neg, and he can't exit the loop because of it. If he makes the unsigned change, he will also need this logic ... good catch on that.
