simple c 's printf problem in mandrake8.0

[eric]

Dear gcc programmers:

  I use the mandrake8.0, test a simple c program
printf("hello world"), it did not print anything, until I add \n at the
end of the string.
such result never happen in redhat7.1 or debian-progeny1.0.  some of
mdk's newbie tell me it is because "our compiler is more stricter than
theirs", I wonder whether it is true, especially the program written and
compiled by the way of redaht or debian may cause error or any
unpredicted result run on mandrke.

  are any file I should install so it can print the "hello world"
without \n?

highly appreciate your tech help
sincere eric
