How do I seperate Punctuations in a sentence with a space between each phrase and punctuation in C++?
原标题:

I want to write a program in c++ that get a sentence and insert a space between each word and punctuation in it! in sed script this is done with this expression:

sed -e "s/,([^0-9])/ , 1/g" -e "s/.([^0-9])/ . 1/g" -e  s/.[ ]*$/ ./g  -e "s/ /   /g" -e  s/?/ ?/g  -e  s/``/ `` /g  -e "s/   /  /g" -e  s/(/ ( /g  -e  s/)/ ) /g  -e  s/ . ([^$])/. 1/g  -e "s/  s/ s/g" -e "s/"([^"]*)"/" 1 "/g" $1 | sed -e "s/"([^"]*)"/``1  /g" 

But I don t khow how i should do this in c++ in windows! for example: should convert a "The question now: Can he act more like hard-charging Teddy Roosevelt." must be converted to "The question now : Can he act more like hard-charging Teddy Roosevelt ." So a punctuation such as - or for example a . in "No." should not spacing in a sentence, but other punctuation that don t rely on a word or a phrase should be spaced.

Since you already know how to handle this using regular expressions I think you can try to use Boost.Regex in order to archive the same with C++.
