Write a program to calculate factorial using recursive function.

#include<stdio.h>
#include<conio.h>
 int fact(int n)
 void main()
{
   int n,f;
   printf("enter a number ");
   scanf("%d",n);
   f=fact(n);
   printf("\n Factorial of %d is %d",n,f");
}
  int fact(int n)
{
   if (n<=1)
   return(1);
   else
   return(n*fact(n-1));
}
