environ points to char ** which holds your environement variables ... All you need to do is iterate over this array of strings and print the values!!!!

Your question history indicates that you are in the process of learning C.
I would be glad to help you code this piece but I wont code it for you.

Also, you should consider managing your open questions and grading history ... 9 Bs out of 10 certainly dont look very encouraging.

another hint,
  That environ pointer which sunny pointer is the third paramenter to the main
also see getenv() if you want to retrieve the value of specfic value.

Paul - I ABSOLUTELY DISAGREE ON DELETING COMMENTS WITHOUT MENTIONING THAT to the others.

As I side note: I'll ask the admins about that conduct, since not only it is impolite and rude, but also unfair and IMO not justified. Not to speak of professionality here.
