Thanks Don! I seem to get closer to understand it. With a simpler test, here is my dissection of the execution:
but I still did not get how putcharTwice( int c) print the chars (now vowels only) twice.
For putcharTwice('e'): (putchar('e') == EOF || putchar('e') == EOF) becomes (0 || 0) so that the else block is executed to return 'e'; but how is 'e' printed twice to have ee with this function?
Thanks again!

}
I wonder, how the syntaxes "f()" and "(*f)()" are treated as same without any error? Is this an improvement or ANSI/ISO... (1 Reply)
