/* Write a program that prompts the user for an integer, then prints the numbers
 * from 0 to that integer (inclusive).  You cannot use the following keywords:
 *
 * if  else  do  while  goto  for  break  
 * continue  switch  default  try  throw  catch
 *
 * You also cannot use setjmp and longjmp (if you know what these are).
 * You also cannot use the ?: operator (it's essentially an 'if-else' statement).
 *
 * In short, your program cannot use any loops. 
 *
 * For a very difficult challenge, do this without using the && or || operators.
