istringstream测试

1.istringstream strcin(str),字符串（str）可以包括多个单词，单词之间使用空格分开

 #include "stdafx.h"
 #include "iostream"
 #include "sstream"
 #include "string"
 using namespace std;

 int _tmain(int argc, _TCHAR* argv[])
 {
     string str = "i am a girl";
     string s;
     istringstream strcin(str);
     while (strcin >> s)
         cout << s << endl;
     system("pause");
     return ;
 }

无论是第一种还是第二种，进行单步调试时，可以看到s每次只输出一个值。

　　若将s中放入vector中可以采用如下方法。
