C + + split string (similar to Boost::split)

Because C + + string does not have the split function, so the string division of words must be written by themselves, it is equivalent to implement a split function it!

If you need to split the word according to a single character, it is good to read it directly with Getline, very simple

1#include <iostream>2#include <vector>3#include <string>4#include <sstream>5 using namespacestd;6 7 intMain ()8 {9     stringwords;Tenvector<string>results; OneGetline (cin, words);
 A Istringstream SS (words); -      while(!ss.eof ()) -     { the         stringWord; -Getline (SS, Word,','); - Results.push_back (word); -     } +      for(auto Item:results) -     { +cout << Item <<" "; A     } at}

If it is a multi-character segmentation, for example,.! And so on, you need to write a function similar to split:

1#include <iostream>2#include <vector>3#include <string>4#include <sstream>5 using namespacestd;6 7vector<Char> is_any_of (stringstr)8 {9vector<Char>Res;Ten      for(auto S:str) One Res.push_back (s); A     returnRes; - } -  the voidSplit (vector<string>& result,stringSTR, vector<Char>delimiters) - { - result.clear (); -Auto start =0; +      while(Start <str.size ()) -     { +         //split based on multiple separators AAuto Itres = Str.find (delimiters[0], start); at          for(inti =1; I < delimiters.size (); ++i) -         { -Auto it =Str.find (delimiters[i],start); -             if(It <itres) -Itres =it; -         } in         if(Itres = =string:: NPOs) -         { toResult.push_back (Str.substr (Start, str.size ()-start)); +              Break; -         } theResult.push_back (Str.substr (Start, Itres-start)); *Start =itres; $++start;Panax Notoginseng     } - } the  + intMain () A { the     stringwords; +vector<string>result; - getline (CIN, words); $Split (result, words, is_any_of (", .?!")); $      for(auto Item:result) -     { -cout << Item <<' '; the     } -}
