如何遍歷字符串中的單詞？ - How do I iterate over the words of a string?

問題：

I'm trying to iterate over the words of a string. 我正在嘗試遍歷字符串中的單詞。

The string can be assumed to be composed of words separated by whitespace. 能夠假定字符串由空格分隔的單詞組成。

Note that I'm not interested in C string functions or that kind of character manipulation/access. 請注意，我對C字符串函數或那種字符操做/訪問不感興趣。 Also, please give precedence to elegance over efficiency in your answer. 另外，在回答問題時，請優先考慮優雅而不是效率。

The best solution I have right now is: 我目前擁有的最佳解決方案是：

#include <iostream>
#include <sstream>
#include <string>

using namespace std;

int main()
{
    string s = "Somewhere down the road";
    istringstream iss(s);

    do
    {
        string subs;
        iss >> subs;
        cout << "Substring: " << subs << endl;
    } while (iss);
}

Is there a more elegant way to do this? 有沒有更優雅的方法能夠作到這一點？
