Create my own archiving utility in C

 (60 points) Write an archiving utility in C that allows you to create an archive, and add, list, and extract files. Call it... gunk. It should have the following capabilities:

 (a) (20 points) ./gunk -a myarchive somefile 

Gunk should add (hence the -a) the file somefile to the archive file myarchive. Subsequent calls to add to the same archive should result in the additional files being added to the archive. 

(b) (20 points) ./gunk -l myarchive 

Gunk should list only the names of the files stored in the specified archive. 

(c) (20 points) ./gunk -e myarchive somefile 

Gunk should extract the named file from the archive, creating a new file with the same name and containing the exact same data as the original and stored files. Careful not to overwrite something you can’t live without.
