- [Instructor] We'll begin learning how to work with files…and directories by getting a big picture view…of the file system.…And it's going to be helpful if we start by taking…a look at the basics of input and output.…Input and output are vital to having a dynamic program.…Otherwise, our programs would run the exact same way…every time they were executed.…Making a program interactive with input and output…makes it more flexible and much more useful.…Now, frequently you're going to see input and output…abbreviated as I/O.…
So if you hear me say IO, I'm referring to input and output.…In our case, we're going to be talking about input…into a Ruby program and output from that program.…In the Ruby essential training courses…that proceeded this one…we've already seen examples of output in Ruby.…We've been using puts and print to send output…either to the command line or to the IRB console.…We've also seen an example of input.…We've used gets to pause a programs execution…and wait for the user to type a line of text…
