What you have seems OK.
In the absence of any loops or decisions, it's just a list of boxes.
> My problem is the second "outFile" line. I am not sure how to correctly add "Name: ", "Id: ", and "Sex: " in the flowchart, as the output for this is all on one line.

Normally, you're supposed to come up with the flowchart, THEN do the code - not the other way round.
