ブーストで文字列をカンマで分割
#include <iostream> #include <vector> #include <boost/algorithm/string.hpp> using namespace std; int main(){ string str="abc,efg,hij"; vector<string> v; boost::algorithm::split(v,str,boost::is_any_of(",")); cout << v[1]; return 0; }
間違ってても突き進む。
#include <iostream> #include <vector> #include <boost/algorithm/string.hpp> using namespace std; int main(){ setlocale(LC_CTYPE,""); basic_string<wchar_t> str=L"abc,efg,hij"; vector<basic_string<wchar_t> > v; boost::algorithm::split(v,str,boost::is_any_of(L",")); wcout << v[1]; return 0; }
#include <iostream> #include <vector> #include <boost/algorithm/string.hpp> using namespace std; int main(){ setlocale(LC_CTYPE,""); basic_string<wchar_t> str=L"テスト,cfg,テスト２"; vector<basic_string<wchar_t> > v; boost::algorithm::split(v,str,boost::is_any_of(L",")); wcout << v[1]; return 0; }
これは実行はできる
#include<iostream> #include<string> #include<vector> #include<boost/algorithm/string.hpp> using namespace std; int main(){ setlocale(LC_CTYPE,""); cout << "hello" << "\n"; wstring IP=L"たぬき.168.きつね.1"; vector<wstring> v; boost::algorithm::split(v,IP,boost::is_any_of(L".")); wcout << v[3]; }
