Simple Recursive Program to find factorial of a given number in C

Finding factorial of a given number is very easy . Recursive code is given below . Consider you are passing a value 5 to this function .
so its execution will be
5*factorial(4)
5*4*factorial(3)
5*4*3*factorial(2)
5*4*3*2*factorial(1)
5*4*3*2*1
=120

Code: (in C)

	int fact(int n)
	{
	if(i<2)
	return 1;
	return n*fact(n-1);
	}
	void factorial(int n)
	{
	if(n<0)
	printf("Invalid Number");
	else
	printf("%d",fact(n));
	}
