  My bad if the following instruction structure's already been hashed
  out in this thread, but I haven't been following the whole convo!

  In my C 101 classes, after we've covered "if" and "else",
  I always throw this program up on the screen and hit the newbies
  with this curveball: "What's this bad boy going to spit out?".

  Well, it's a blue moon when someone nails it. Most of them fall
  for my little gotcha hook, line, and sinker.

#include <stdio.h>

const char * english( int const n )
{ const char * result;
  if( n == 0 )result = "zero";
  if( n == 1 )result = "one";
  if( n == 2 )result = "two";
  if( n == 3 )result = "three";
  else        result = "four";
  return result; }

void print_english( int const n )
{ printf( "%s\n", english( n )); }

int main( void )
{ print_english( 0 );
  print_english( 1 );
  print_english( 2 );
  print_english( 3 );
  print_english( 4 ); }
