C program to find factorial of a given number using recursion

#include<stdio.h>
int fac(int n);
int main( )
{
     int n, fact;
    
     printf("Enter a number");
     scanf("%d",&n);

     fact=fac(n);

     printf("Factorial of number %d is %d", n, fact);

  return 0;
}

int fac(int n)
{
     if(n==0 || n==1)
         return 1;
   
     else
          return(n*fac(n-1));
}
