如何将string中的字母每遇到','，就把逗号前面是内容存进容器中

C/C++ code

string a = "123，456，7890";vector<string> Va;//将a中的123，456， 7890(不要逗号)，依次push_back进Va中 ？

C/C++ code

#include<iostream>#include<sstream>#include<string>#include<iterator>#include<vector>using namespace std;int main(){    string a = "123,456,7890";    vector<string> va;    stringstream ss(a);    string number;    while(getline(ss,number,','))    {        va.push_back(number);    }    copy(va.begin(),va.end(),ostream_iterator<string>(cout,"\n"));}
