Lesson goal: Reading from a data file

In the last lesson, you learned how to open a file. Now, let's learn how to read in some data contained in the file.

To read data from a file, you can used the file_read function, that works like this:

data=file_read(handle)

Move the mouse over a dotted box for more information.

Now you try. Run the code and see if you can read the first line of data from the file `sample.dat`.

Type your code here:

See your results here:

This code will not run! Fill in the file name in the file_open line, and what will you pass in to the file_read function?

If everything works, you should see a number appear on your screen, which is the first number in the file sample.dat. Dismiss.
