Compares characters within strings

Hi.

I want user to input two words, and then compare The two words. If The words differ in characters: n; If they are the same, print 'same'.

Here is my code.

letter1 = input("Please enter a string: ",'s');

letter2 = input("Please enter a string: ",'s');

for i = 1:3

if (letter1(i) ~= letter2(i))

fprintf("The words differ in characters: %d\n",i)

else

fprintf("same\n");

end

end

Sample test:

Please enter a string: cat

Please enter a string: cat

same

same

same

The problem I encountered was how to print 'same' only once?

letter1 = input("Please enter a string: ",'s');
letter2 = input("Please enter a string: ",'s');
count = 0 ; 
for i = 1:3
    if (letter1(i) ~= letter2(i))
        fprintf("The  words differ in characters: %d\n",i)
    else 
        count = count+1 ; 
    end
end
if count == length(letter1)
    fprintf("same\n");
end

The above fails if letter1 and letter2 has different lengths.

You need not to do all that, read about strcmp, isequal
