stdout is buffered by default while stderr is not. The three ways to flush a buffered stream are filling it up ("hello-out" is unlikely to do that), printing a newline (which you don't), and calling fflush.
flushall isn't guaranteed to be available as it's a non-standard extension.
Besides, you can achieve the same effect as flushall (assuming it does what one might expect) with fflush(NULL).
Actually, it is and but I have experienced myself, somewhat inconsistent behaviour of C++ compilers where they give
inaccurate result on first compilation mostly one rebuilding in file operations in C.
So, I was just rebuilding the object file using a new function.
Just Thanks for refreshing my memory about that alternate and somewhat tricky function.
>Actually, it is
Prove it. I can prove otherwise by showing the lack of a definition for flushall in the C standard, so you're already in a hole.

While at a glance this (and all of your other posts) look like English, they're largely incomprehensible.
