Thread: facutly method isn't working

Hi guys

I'm working on the issue to understand pointers and addresses in c programming.
Unfortunately I don't see the problem here. For a c programmer my question should be easy to response

Code:

#include<stdio.h>
void factorial(int*);
int main()
{
	// the program calculates faculty
	int n; 
	int *pn;
	printf("Enter a positive integer which you want to facultate\n");
	scanf("&d",&n);
	pn = &n; 
	factorial(pn); 
	printf("result: %d", n);
	return 0;
}

void factorial(int *px)
{	
	int k,tmp;
	tmp = *px;
	
	if( *px == 0)
		tmp = 1;
		
	for (k=1;k<=*px;k++)
		tmp = tmp * k;
		
	*px = tmp;
}

I can build/compile the file. But the result is: 3265920 for every positve integer I want to facultate ..

thx for helping me!

You might want to initialise to 1 instead of *px

It doesn't work either. The result is still: 3265920
