How do I output data from a txt file?

Let me explain, I want to take these messages from a .txt file:

Congratulations!

Way to go!

You're amazing!

Fantastic!

Wow!

So far I have this code:

function [asciifromfile] = getPhrase ()
g=rndInt(1,5);
fileID=fopen('CSE101lab5Congrats.txt',r);
asciifromfile=fread(fileID);
end

I want it to display one of the messages, depending on whether or not g=a number between 1 or 5. For example, if g=1, output Congragulations!

Hello John

Here is the modified version of your function to read one line from the file each time and store it to retrive it later:

function [txtLines] = getPhrase()
    fileID = fopen('CSE101lab5Congrats.txt'); % open the text file
    i = 1;
    while ~feof(fileID) % while not reaching the end of file
        asciifromfile = fgetl(fileID);% use fget1 to read a line from the text file
        txtLines{i,1} = asciifromfile;% store each line from the file in a cell
        i = i+1;
    end
    fclose(fileID);
end

Then, to call it:

[txtLines] = getPhrase();
g = randi(5)
disp(txtLines{g})

And here is an output example:

g = 4
Fantastic! 

Hope this would help.

If you want to dynamically select any of the lines:

disp(txtLines{randi(end)})

This code will select any of the lines, even if there are more than 5.
