Writing contents cell into a txt file

I have 3 words in one cell (e.g. fox, cat, dog). How would I write all of the contents of that cell to a text file so that all 3 words are on one line and there is a space between each word? I have a loop where I am generating multiple 3 letter word combinations from a word list and then writing them into one text file (appending the file). The text file should look like this:

fox dog cat boy man jet try set buy etc...

c={'dog','cat','fox'};
fid=fopen('out.txt','w+t');
for k=1:10
    fprintf(fid,'%s ',c{:});
end
fclose(fid);
