but I still did not get how putcharTwice( int c) print the chars (now vowels only) twice.
Because putchar isn't returning EOF.
From man putchar:
Code:
RETURN VALUE
       fputc(),  putc()  and  putchar()  return  the  character  written as an
       unsigned char cast to an int, or EOF on error.

So if you're printing C, it ends up testing 'C' == EOF, which evaluates to 0, allowing it to reach the second part, testing 'C' == EOF again, which is false again.
