    quick question

    Hey my book has an excercise that states the following:

    Examine the following program carefully. What is printed?

    #include <stdio.h>
    int main(void)
    	return 0;
    I ran it and it prints Hello? this seems to be to easy. Am I missing something?

    Yes. The closing parentheses on the second printf.

    On an output stream, fflush causes any buffered but unwritten data to be written; On an input stream, the effect is undefined. It returns EOF for a write error, and zero otherwise. fflush(NULL) flushes all output streams.

    Can you now figure out what the consequence of closing stdout is?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    The stdout stands for STANDARD OUTPUT and when we close stdout the GOODBYE is not shown on the screen.

    That's all hidden logic is there.
