To find factorial of the number using recursion

If we want to find the factorial of any num using recursion theorem&nbsp; this can be done in this way:<br />
for eg factorial of 5=5*4*3*2*1 <br />

the source code of the program is :<br />
<br />
<br />

	#include<stdio.h>
	#include<conio.h>
	int factorial(int);
	void main()
	{
	int num;
	printf("enter the number whose factorial is to be find");
	scanf("%d",&num);
	fact=factorial(num);
	printf("the factorial of the input num is %d",fact);
	getch();
	}
	int factorial(int n)
	{
	if(n==0)
	return (1);
	else
	return(n*fact(n-1);
	}
