If you haven't yet pushed this to remote, run
  git reset --soft HEAD^
to only undo the commit. ex1s.c will still include your changes and be 
scheduled ('staged') for the next commit. If you want to undo all your 
changes including ex1s.c, use
  git reset --hard HEAD^

Note that once you pushed your commits to the remote, you should not 
attempt to change these commits.

Best regards,
