trivial problem with fork

Hi All,

I know this is very trivial. Might be am missing something out.

The program is a simple pipe, which writes "hello" to the child and the
child prints "hello".

When I run the code I get to see "hello" on stdout and then get the prompt
but am not able to see it.

What i mean is say the prompt is prompt>

prompt>./a.out
prompt>hello

I get a prompt and then see hello
and I don't see the prompt after hello.

Actually what I expect is

prompt>./a.out
helloprompt>

But if I type "ls" or anything after hello it shows the output. So it means
that the prompt is there.

What I mean is 
prompt>./a.out
prompt>helloecho hi
hi
prompt>

Hope I have been clear. Thanks.
Gowri.
