Is the modulus operator (%) useful? //. What is the modulus operator useful for? Why don't new programmers use it more often, even after they learn what it does?

This video provides a few useful scenarios when you might want to start using it in your programs, specifically when trying to determine even division and manage circular buffers.

The examples are in C, but the use of the operator applies easily to C++, java, python, ruby, and most other imperative languages.

Welcome! I post videos that help you learn to program and become a more confident software developer. I cover beginner-to-advanced systems topics ranging from network programming, threads, processes, operating systems, embedded systems and others. My goal is to help you get under-the-hood and better understand how computers work and how you can use them to become stronger students and more capable professional developers.
