        Introduction to Programming in C       



Assignment 3_Question 3:


Write a C program to list all the factorial numbers less than or equal
to an input number n.

A number N is called a factorial number if it is the factorial of a
positive integer. For example, the first few factorial numbers are

   1, 2, 6, 24, 120, ...

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

Input
-----
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;
  
}
