Checking whether the word in .txt are also in .txt

How do you check if the words in the email.txt are in the lists.txt. Also there are some misspelled words in email.txt so I have to print out misspelled words.

Using elementary functions (fopen, fclose, fgetl, ischar, isempty, lower, find, strcmp, intersect, max, length, sort, input, str2num, fprintf, etc..)

% read in the lists.txt

fid=fopen('lists.txt');

while 1

    tline = fgetl(fid);
    if ~ischar(tline), break, end
    disp(tline)      
end
fclose(fid);

% read in the email

fid=fopen('email.txt');

while 1

    tline = fgetl(fid);
    if ~ischar(tline), break, end
    disp(tline)      
end

How does this differ from your earlier question at www.mathworks.co.uk/matlabcentral/answers/64602 ?

The ismember() command might be helpful.
