C++11 lambda functions capture variables declared in their outer scope by value-copy or by reference. This means that value members of a lambda cannot be move-only types. [ 13 ] C++14 allows captured members to be initialized with arbitrary expressions.
The rules are effectively the same as inline functions __has_include, allowing the availability of a header to be checked by preprocessor directives [25] Value of __cplusplus changed to 201703L [26] Exception specifications were made part of the function type [27] Lambda expressions can capture "*this" by value [28]
In such a case, a common solution is to create a clone (or similar) virtual function that creates and returns a copy of the derived class when called. A member function can also be made "pure virtual" by appending it with = 0 after the closing parenthesis and before the semicolon.
In C++ computer programming, copy elision refers to a compiler optimization technique that eliminates unnecessary copying of objects.. The C++ language standard generally allows implementations to perform any optimization, provided the resulting program's observable behavior is the same as if, i.e. pretending, the program were executed exactly as mandated by the standard.
