First, you posted the exact same article three times. Please don't do
that. (Apparently Google somehow makes it easy to make this mistake.)

Knowing how to do what? There are some errors in your program
(missing "#include <stdio.h>", "main()" should be "int main(void)",
the result of the sizeof should be cast to int for use with "%d"), but
apart from that I don't know what you're asking.

Rarely, it, (Google Groups), reports a posting failure while the post
had actually succeeded. The unassuming poster then retries, thus
posting twice, or more.

Whenever such an "error" is reported, I actually check the thread,
after a gap of a few minutes, to make sure that post hasn't silently
succeeded, before attempting to post again. Many posters don't bother
to take this much trouble.
