Hi, If the numbers 1 to 5 are written out in words: one, two, three, four, five, then there are 3 + 3 + 5 + 4 + 4 = 19 letters used in total. Write a function called number2letters that returns the number of letters needed to write down the number

Hi, Really no idea how to start this question. PLease help.

You can do that by using this custom function

Here Answer:

n=input('Enter the number: ');
words_number=num2words(n);
disp(words_number);
str=upper(words_number(:));
AZ='A':'Z';
count=sum(ismember(str,AZ));
fprintf('The numbers of letter: %d',count);

%Make the function yourself, I hope now you can do that. Got the idea from here

Here function is:

function count=num2letters()
n=input('Enter the number: ');
words_number=num2words(n);
disp(words_number);
str=upper(words_number(:));
AZ='A':'Z';
count=sum(ismember(str,AZ));
fprintf('The number of letter is %d',count);
end

Call like

k=num2letters()

The function will ask to enter the number.
