Find factorial of a number using recursion in c program

#include<stdio.h>
 int main(){  
 int num,f;  
 printf("\nEnter a number: ");  
 scanf("%d",&num);  
 f=fact(num);  
 printf("\nFactorial of %d is: %d",num,f);  
 return 0;
 }  
int fact(int n)
{  
  if(n==1)      
  return 1;  
  else     
   return(n*fact(n-1)); 
 }
