Just as a reminder, up next we will be covering logic, conditionals, loops, and how to make more complex programs. But before this, I think it is important to make sure we have the previous blogs down well. These next blogs and previous blog will quiz you on some parts of C. If you have a hard time answering these question, you might want to review your notes. Are you new here? Start at the beginning, Intro to C!

1. What is the % operator called and what does it do?
2. What is the difference between i++ and ++i?
