completed main activity.
completed the bonus activities for ex1.
changed naming convention for excercises from XX to exXX. eg: 01 is now ex01
made a mistake in the last commit, and did not properly remove previous directories. That has been fixed.
finished ex02.
made my make file needlessly complicated as the bonus activity asked.
made a symbolic link to hello.c in ex01 for use in the make file of ex02. I couldn't figure out how to get the make file to point to a directory outside the make root.
finished ex03, and rebuilt the make files as they were they accidentally made the main file into an object, so now I take the object and simply rename it as it actually does work.
