c++ - Removing capitals and lengthening contractions in a string -


i'm trying replace capitals lengthening contractions used in string. i'm trying find fastest , efficient approach.

here attempt, not working:

note: ur 'unrefined input'

//removing capitals std::transform(ur.begin(), ur.end(), ur.begin(), ::tolower); //removing contractions std::replace( ur.begin(), ur.end(), "it's", "it is");

here what's included in program

#include <iostream> #include <string> #include <algorithm>

your post contains 2 different questions, both of duplicates, , not saying what "is not working".

the way writing correct if using ascii characters only. see this answer more details supporting locales , other encodings.

replacing contractions

this hard if want efficient. if want replace each contraction 1 one, shouldn't use replace (it replace characters, not substrings). have @ this answer.
