C++ 字符串分割，分割到vector中

#include <string>#include <vector>using std::string;using std::vector;int splitStringToVect(const string & srcStr, vector<string> & destVect, const string & strFlag);int main(){    string str = "asdasdas \n, sadasd\n, ssdddsrr\n \n \n ss\n";    vector<string>   destVect;    splitStringToVect(str, destVect, "\n");     //以"\n"为标记，分割字符串到vector中    return 1;}int splitStringToVect(const string & srcStr, vector<string> & destVect, const string & strFlag){    int pos = srcStr.find(strFlag, 0);    int startPos = 0;    int splitN = pos;    string lineText(strFlag);    while (pos > -1)    {        lineText = srcStr.substr(startPos, splitN);        startPos = pos + 1;        pos = srcStr.find(strFlag, pos + 1);        splitN = pos - startPos;        destVect.push_back(lineText);    }    lineText = srcStr.substr(startPos, srcStr.length() - startPos);    destVect.push_back(lineText);     return destVect.size();}
