你可以轻松地定义函数模板来将⼀个任意的类型转换到特定的⽬标类型。例如，需要将各种数字值，如int、long、double等等转换成字符串，要使⽤以⼀个string类型和⼀个任意值t为参数的to_string()函数。to_string()函数将t转换为字符串并写⼊result中。使⽤str()成员函数来获取流内部缓冲的⼀份拷贝：te...
例如,需要将各种数字值,如 int、long、 double 等等转换成字符串,要使用以一个 string 类型和一个任意值 t 为参数的 to_string()函数。to_string()函数将 t 转换为字符串并写入 result 中。使用 str()成员函数来获取流内部缓冲的一份拷贝: template<class T> void to_string(string & result,const T& ...

stringstream is a stream class to operate on strings. It implements input/output operations on memory (string) based streams. stringstream can be helpful in different type of parsing. The following operators/functions are commonly used here
