You don't have anything in your code that needs a header.
If you changed printf() to fprintf (stderr, "hello\n"); then it will
complain until you #include <stdio.h> to define stderr.

Dear List,
I am relatively new to C...
I am having difficulty understanding the following: ( I am reading
Brian Overland's "C in plain English")
As an illustration, he shows how to enter something like this, without
anything else.
void main() {
printf( " foo bar ! \n");
}
... and explains how to C this is like any other function that needs
to be defined before being used, and hence the need to add " #include
<stdio.h> " in the first line.
Well, I just typed it without the # include and ......printed just
fine, although I had expected to receive a warning "undefined etc
etc". . I did this both in Terminal and Xcode and got the exact same
warning but both printed ok......
I know there are real C gurus on the list...any explanation as to why
it seems to work without adding the includes on Xcode or terminal?
Tks
