C++提取出字符串中的单词

方法：

将输入的string对象转换istringstream对象从而像输入流一样处理字符串

提取函数是split_String(vector<string> &s,string str)

#include<iostream>
#include <sstream>
#include <string>
#include<vector>
using namespace std;
void split_String(vector<string> &s,string str);
int main()
{
	vector<string> ves;
	string str="the quick red fox jumps over the slow red turtle";
	split_String(ves,str);
	for(auto v:ves)
		cout<<v<<endl;

	return 0;
}
void split_String(vector<string> &ves,string str)
{
	istringstream ss(str);
	string s;
	while(ss >> s)
	{
		ves.push_back(s);
	}
}
