Hey can you help me figure our why my counter isn't working?

If i input find_consonant('tiger') I need MATLAB to count all of the letters that are not a, e, i, o, u. So the answer should be 3 but my code is not counting right. Thanks for any suggestions.

function count=find_consonant(word)
count=0;
for i=1:length(word);
    if word(i)~='a'||word(i)~='e'||word(i)~='i'||word(i)~='o'||word(i)~='u'
        count=count+1;
    else
        count=count;
    end
end

Thanks, that worked. I don't see why it would make a difference, the OR comparison make more sense to me in this case. How did you come to that solution?

I came to that solution because there were no other candidates. OR will clearly not work, because you are then requiring only that the given letter be different from at least one of the vowels, be it A or E or I or O or U. Any letter will in fact satisfy this. A consonant, however, must be simultaneously different from all of them.
