int main()
{
while(1)
{
fprintf(stdout,"hello-out");
fprintf(stderr,"hello-err");
sleep(1);
}
return 0;
}why is that i am getting heelo-err instead of hello-out
Try to use fflush() function.
May be that will solve your problem.

Did you use it correctly?
fprintf(stdout,"hello-out");
fflush(stdout);
fprintf(stderr,"hello-err");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.
use flushall() instead of that.
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.

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.
