#include <stdio.h>
main()
 {
    int ch;
    while ((ch = getchar()) != EOF)
      if (ch != ' ')
	putchar(ch);
 }

However, contemplate what will happen to the correctness of either of
the above programs if passed through such a filter. They will _BOTH_
break, either failing to compile or generating incorrect code if they
do compile.
