Compares characters within strings
显示 更早的评论
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.
