Hello, in this video, we are going to look at the end of file function. So this basically allows us to check when we've hit the end of the file. So we've got this f gets function which reads a single line, like, you know, like you can see there. But what if it isn't just in a free line? What is 100,000 More importantly, if we don't know, maybe the user created file, the user uploaded the file and we want to you know, print out the content or you know, get the content for whatever reason, then, what we can do is using the end of file function, and to do these really simple, you just do while the while it hasn't reached the end, we want to keep getting new lines a wall, f e o f, which is file end of file, and you need to specify the file right here.

So this will keep basically track of where it is in the file. And instead of doing all of these lines, We can basically just do the war. Now, if we do the one like so, if we reload, we should get the same result. But what will happen if I add a new line? so epic new line? Hello, awesome club, I did save raw matter what's in there, but it's several new lines.

And it's still work, because we dynamically check if it's the end of the fall. And if it is the end of the fall, then this, you know, will stop running. But that is one of the use cases and probably the most important use case of the end of foil function which allows you to check Have you got to the end of fall? If so, you know, there's no more data left. So that's it. If you have any questions, you know where I am, feel free to pop me a message.

And as usual, I look forward to seeing you in the next video.
