How to get and unget input from streams in C (getstring, fgetc, ungetc) // Reading a line from a file or stdin seems super basic, but a lot of students get hung up in the details. This video shows you how to get input from a stream, file, or pipe, using fgetc and ungetc to make your own function like the getstring function in Harvard’s CS50 course.

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.

About me: I’m a computer scientist, electrical engineer, researcher, and teacher. I specialize in embedded systems, mobile computing, sensor networks, and the Internet of Things. I teach systems and networking courses at Clemson University, where I also lead the PERSIST research lab.
