so for ex in a str= i have an apple
and we want to see how many a and remove them we would use
str1= 'a'
ind = strfind(str, str1)
str(ind) = ''
how would we use a loop for this?

str1= 'a'
ind = strfind(str, str1)
str(ind) = ''

s = 'I have an apple';
[a,b] = regexp(s,'a','split');
numA = length(b);
sentenceWithoutA = strjoin(a);

You would probably get a chuckle out of your teacher if you handed in that loop. Also, flagging is not doing what you think. It does attract the attention of site administrators, but it is more likely flags will be dealt with by high reputation members, so exactly the people whose comments you are flagging.
