Get Each Word from a string

Usually, we would like to get each word from a string, for example, str is the string type, it likes " abc  defg   hijk   ". You want to print every word from this string respectively, is there any good way? Of course, we can make it by using some functions, such as find_first_of, find_first_not_of etc. Finally, there are some other ways to complete this.

/* Make the word of str into the vector and print it out. */ #include <iostream> #include <string> #include <vector> // using std::cin; // using std::cout; // using std::endl; // using std::string; // using std::vector; using namespace std; int main() { string str(" abc defg hijk "), strWord; cout<<"str:"<<str<<endl; vector<string> svec; string::size_type begin=0, end=0, wordLen=0; while ((begin=str.find_first_not_of(' ',end))!=string::npos) { end=str.find_first_of(' ',begin); if (end==string::npos) { wordLen=str.size()-begin; } else { wordLen=end-begin; } // save each word strWord.assign(str.begin()+begin,str.begin()+begin+wordLen); svec.push_back(strWord); } // print out each element for (vector<string>::iterator iter=svec.begin();iter!=svec.end();++iter) { cout<<*iter<<endl; } return 0; } /* output: str: abc defg hijk abc defg hijk Press any key to continue */

#include <iostream> #include <sstream> using namespace std; int main() { string str = " abcd efg hi lwsi "; istringstream is(str); string word; while (is>>word) cout<<word<<endl; cin.get();// pause return 0; }

#include<iostream> #include <sstream> #include<vector> #include<iterator> using namespace std; int main() { using namespace std; stringstream ss; ss<<" abcd efg hi lwsi "; vector<string> vec; copy(istream_iterator<string>(ss), istream_iterator<string>(), back_inserter(vec)); copy(vec.begin(), vec.end(), ostream_iterator<string>(cout, "/n")); system("pause"); return 0; }
