If the program ends properly, I think the output *has* to be flushed,
(At least, it does in most cases) but for example, if your program
makes a segfault, you will probably loose the contents of the output
buffer.
in
printf("Hello\n");
f();
printf("world");
g();
if the output is just "Hello", and segmentation fault, the crash may
have occured in f() or g() ...
That's why its generally a good advice to put "\n" at the end of any
debug/test output.
