Reference foldingReference folding occurs when the paradigm is programmed.void f(T&& param);f(10);int x = 10;f(x);Both of these can run successfully.Due to the existence of an undetermined reference type of t&&, when it is used as a parameter, it

Reference:std::string to char*C + + converts std::string to char*There is currently no method for direct conversion. The C-style string must be obtained through the method of the string object c_str() :Note that this method returns a type const char
