If you don't want to spend $$$ to buy that book just to look up the answer to your question, you could try using stringstream class, or use std::string's find method in a loop to locate each of the spaces

Help with Code Tags

(Toggle Plain Text)

while not done
    check if the string has a space
    if not, then this loop is done
    call substr to extract the word into another std::string object and insert this into a vector of strings.
    call substr again to remove the word from the original string
 end of loop

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

Welcome aboard. If you have specific problems when trying to do a program...please post the source code here along with what you think may be wrong. Also post the errors you get, so we can take a look and help you. We are not in the business of doing your home-work for you! You must TRY/show some effort!!

}

this is not working because we have ti implement it usin g strings...and i am not able to do this...my whole socket programming project is complete...but i am not able to form packets...

Why you shouldn't use structs with packets

Ohhh that was really mean

We (or me at least) do lead normal lives like everyone else. I for one do not sit at my computer 24/7 waiting for someone to post some code without code tags.
