You can't write to stdin: it is a read-only stream. It would be the equivalent of writing to your mouse and expecting the user to read the message...
You could use fprintf to write to stdout:

fprintf(stdout, "Enter the data\n");
fgets(buffer,250,stdin);

But printf is the equivalent of that anyway - many implementations do exactly that: call fprintf from printf with stdout as the stream parameter.

This is (at least) the third time you have asked this question, and the answer remains the same:
1. You cannot write to stdin.
2. You cannot read from stdout.

I get the distinct impression that your question does not really explain what you are trying to do, so maybe a bit more detail on what problem you are trying to solve would get you a better answer.
