**1, 2, 6, 24, 120, ...**

***Note* - We do not list the factorial of 0.**

**A positive integer, say n.**

**Output**

**------**

**All factorial numbers less than or equal to n.**

**PROGRAM:**

```
#include<stdio.h>
int factorial(int f)
{
if(f==1)
return 1;
else
return f*factorial(f-1);
}
int main()
{
int n,l=1,g=2;
scanf("%d",&n);
while(n>=l)
{
printf("%d ",l);
l=factorial(g);
g++;
};
return 0;
}
