Thread: C++ Beginner; need help with IsPerfect >.>

Yeah, I picked up an old C++ textbook about a week ago and it seems pretty interesting. Using A Computer Science Tapestry by Astrachan. Anyway, I need help with the boolean, IsPerfect. I've gotten this far, but I just can't seem to fix it up.

Code:

bool IsPerfect(int n)
{	
	int sum = 0;
	int x;
	int divisor;

	x = n;

	while(x > 0)
	{
		divisor = x;


		if(n % divisor == 0)
		{
			sum += divisor;
		}
		x--;
	}

	if(sum == n)
	{
		return true;
	}
	else
	{
		return false;
	}
}

Note: I am basing this off the textbook's example of IfPrime, so any help would be appreciated. Also running a second cpp file for the purpose of testing this boolean. Thank you.

Yeah, thanks. I actually got rid of X since it was actually pretty much just divisor (figured divisor served as a countdown or method to exit the loop as well). And instead of having X getting smaller towards 0, I changed it to the divisor getting bigger towards N or specified value. Thanks.
