C++ 实现split函数

#include <iostream>
#include <vector>
#include <sstream>
using namespace std;

vector<string> split(string s,char token){
    stringstream iss(s);
    string word;
    vector<string> vs;
    while(getline(iss,word,token)){
        vs.push_back(word);
    }
    return vs;
}


int main()
{
    string s1 = "aaa,sss,ddd,fff";
    vector<string> s2 = split(s1, ‘,‘);
    cout << s1;
    for(int i=0;i<s2.size();i++)
    {
        cout<<s2[i]<<endl;
    }
    system("pause");
    return 0;
}
