can anyone help me... Write a MATLAB script (called count.m) which reads a string from standard input and then counts the number of words in that string

Try this.

out = count('here is my question', 'here is the effort I put in to answering it')

Answer 1

[John BG]

assume only spaces, comas, full stop, .. are used between words but not before the very first word and the very last word, then the amount of words is the amount of separators +1.

The most simple version of the script you want would be:

str1='What have you done so far? Please post your code and ask specific questions about it. Then we can offer suggestions and corrections'

amount_words=numel(strfind(str1,' '))+1

amount_words =
    23

hey it works :)

you can then start refining finding ':' ';' '?' that may be isolated and might be counted as words yet they shouldn't.

Note: feel free to ignore all sorts of comments telling that you have to do your homework, and telling you how to ask questions.

[David Barry]

• 1) This fails if there is more than once space between words.
• 2) Do not tell him to ignore our advice. He needs to learn how to use the forum correctly so that he can benefit in the long term and actually learn MATLAB.

Hint:

str = 'i need help with my homework'
words = strsplit(str, ' ')
numWords = length(.......

Use inputdlg() to get the string from the user. See its example in its help.
