How do I ignoring '\n' at the end of the text file that was created?

Hello I created a text file called phonenumbers using the strings that gave true for the condition that I set. I used

 fprintf(output, '%s\n', line);

to print it on the output file. The only problem is when I compare the file I created with the solution file, I get one extra new line at the end of the file. I am only suppose to have 11 lines but I get 12 lines. How do I fix it. I also have a screenshot below.

Thank you.

You are appending that extra line. What you can do is change:

    fprintf(output,'%s\n',line)

to

    fprintf(output,'\n%s',line)

after adding the first line using

    fprintf(output,'%s',line)

Example Code:

    lines = {'firstPhoneNumber','secondPhoneNumber','thirdPhoneNumber'}; 
            for k = 1 : length(lines)
              line = lines{k};
              if(k==1)
                fprintf(output,'%s',line);
              else
               fprintf(output,'\n%s',line);
              end
            end
