Reading and Writing Raw Bytes to Files in C

How to open, read, write, and close a file in C is often taught in a way that leads to a fundamental misunderstanding of what is happening when these operations are performed. Typically, the lesson leaves students with the impression that the data types themselves are being written into a file, rather than the raw bytes that store those data. In this video, I demonstrate how to read and write to files in C as well as how to do so with raw bytes.
