All language subtitles for 20. Exercise 4 - Reading numbers from a file [Solution]

All righty, so I hope you've given it a little bit time on your own to solve it.

Now we are going to do it together, so let's modify here in the open.

Instead of writing, we will read from this file.

Right.

So the the the the working mode should be reading from a file.

F.P. will point to this file and we will be able to read from it.

So how should we read?

What do you think?

What do you think should be specified here?

Well, basically we should iterate also over some for a loop, let's say equals to one eye is long is

less than or equal to ten and I plus plus OK, inside of these for a loop, we are going to do two things.

The first thing that we are going to do is to read the information stored there.

How are we going to do it using the F Cunniff function now we are going to specify here what is it expect

to receive a pointer or to file, which is F.P..

Vaneta expects to receive some format.

Right, similar to how the printed function works.

So let's use your percentage and percentage the.

Reading to values of an integer type and storing them inside, what are should we store them?

Let's create also variables and let's call it ain't number one and number two.

And now we are going to come here and specify store them inside the address of number one and inside

the address of number two.

So reading from these files, where is this file?

Here it is, reading values from here, storing it inside, number one, this one inside them two and

then to inside and one for inside them two and so on and so forth.

OK.

So, yeah, here we return value is ignored.

I, I don't really want to get into this right now, but basically we are just going through this information

and on every iteration, what are we expected to do to print the result to the screen?

So print have a basic print that you already know, read, let's say percentage and percentage and specify

here, I don't know, some backslash and one.

And number two, that's it, that's eight guys reading value by value from the file and printing it

to the council.

So let's see if it corresponds to what I'm saying, one, one, two, four, three, nine and so on.

And here is the file.

You can see that they are almost identical, right?

They are identical, actually.

One one.

So, yeah.

Now, you know, and you practice a little bit on your own how the F scanner function works.

Very important that you will know the syntax, that you will know what come to you for what comes after

and so on and so forth.

So, as always, thank you guys for watching, keep on practicing and let's move on.

Enjoy.
