 *
 * Lab 0: Getting to Know You
 * --------------------------
 *
 * Welcome! I'm excited to have you in class and am looking forward to getting
 * to know you over the course of the semester. This first lab assignment has
 * two goals:
 *  - For you to tell me a little bit more about yourself
 *  - Trying out the assignment submission process
 *
 * Edit this .c file to provide your responses, make sure it compiles and runs,
 * and then check it into github to submit. That's all there is to it!
 *
 * To compile:
 *  cc lab0.c -o lab0
 *
 * And then run:
 *  ./lab0
 *
 *
 *  Don't have a C compiler on your machine? No problem. You can use:
 *
 *   - https://replit.com/languages/c
 *   - https://pythontutor.com/c.html
 *
 *  ...And probably millions more out on the web. Just be aware that you won't
 *  be able to get away with using an online compiler for the rest of the work
 *  in this class! :-)
