#include<conio.h>

void main()

  {

    int n,f=1,i;

    clrscr();

    printf("\n Enter positive number: ");

    scanf("%d",&n);

    if(n<0)

    printf("\n You have entered negative number");

    else if(n==0)

    printf("\n Factorial of %d is 1",n);

    else

    {

     for(i=1;i<=n;i++)

     f=f*i;

     printf("\n Factoria of %d is %d",n,f);

    }
