C++ 分割字符串

按照标识符分割字符串，分割好的字段保存至数组，贴出示例代码：

#include <iostream>#include <string>#include <vector>using namespace std;std::vector<std::wstring> split_string(std::wstring &szInput, std::wstring &szToken){std::vector<std::wstring> result;int pos = 0;int begin = 0;const int size = szToken.size();while(true){if ((pos=szInput.find(szToken,begin))==std::wstring::npos){result.push_back(szInput.substr(begin));return result;}result.push_back(szInput.substr(begin, pos-begin));begin = pos + size;}}int main (){wstring szInput = L"hello$yy.com$this$is$test$by$kandy";std::vector<wstring> data = split_string(szInput, wstring(L"$"));for (int i=0; i<data.size(); ++i){wcout << data[i].c_str() << endl;//printf("%ls\r\n", data[i].c_str());}return 0;}
