Well I have absolutely no idea what you are trying to say. Please can you explain what is wrong, what you want, or what you need. All I can see is some code that isn't explained.

Also, please use [code] tags. It makes it easier for people to read and understand your code, as well as making the forums look neater.

Note: I added the [code] tags for you this time, to make it easier for other people to help you. But I won't in the future.

actually while running the program iam facing these errors i did'nt created this program my frnd created it so i don't know mch.
errors iam faceing are:-
1. functions containing for are not expanded inline.
2. functions containing missing return statements are not expanded.
3. tye name expected.
4. declaration missing ;
5. undefinid symbol 'a'
6. 'addobjects' is not a member of 'list '.

You should probably hope your prof doesn't care enough about his/her assignments to use Google. Otherwise, you're quite busted for 1) plagiarism, and 2) having no idea how "your own" program works.
