►Lesson Description: In this lesson we take a look at std::cerr and std::clog which write to the stderr file handle. These are also globally defined objects provided in the iostream header. These are important ways to write output to ensure that we log error messages. In this lesson we'll also cover buffered versus unbuffered output and why that matters for error handling code. Finally, I'll also talk about stdin, stdout, and stderr which belong to every process, and I'll show you how to redirect output on the terminal for logging purposes. As always, feel free to bring up any questions and discuss what you've learned!
