1.头文件:#include<sstream>
2.stringstream是C++提供的串流(stream)物件
3、clear()重置流的标志状态;str()清空流的内存缓冲,重复使用内存消耗不再增加!
1 #include<string> 2 #include<sstream> 3 #include<iostream> 4 using namespace std; 5 int main() 6 { 7 stringstream sstream;//定义流 8 sstream << "first" << " " << "string,"; 9 sstream << " second string"; 10 cout << "strResult is: " << sstream.str() << endl;//str()方法能够将流转换为string,但这不影响原sstream 11 sstream.str("");//清空内存 12 sstream << "third string"; 13 cout << "After clear, strResult is: " << sstream.str() << endl; 14 return 0; 15 }
