How to accumulate a result using for_each in C++? Stack Overflow
Moves the elements in the range [first,last] into the range beginning at result. // std::move since c++20 } return init; If left to type inference, op operates on values of the same type as init which can result in unwanted casting of the iterator elements. The value of the elements in the [first,last] is transferred to the elements pointed by result. Used to move the resources from a source object i.e. Struct fileinfo { std::string filename_; Provide details and share your research! Avoid functions such as create, init, destroy, copy and clone. In fact, not only that, but when implementing e.g. So within globals_io.cc, std::cin/std::cout/std::cerr are nothing but char arrays aligned to match the requirements of istream/ostream.yet the iostream header and ios_init.cc declares them as externs that are actual istream/ostream objects, and uses them as such (assuming [correctly] they haven't been initialized in the latter case, since it placement news all.
} [n]rvo doesn't apply to return result;, but at least it's implicitly moved, rather than copied. Inpoc::create should actually be a regular constructor. Std::move merely casts its argument to an rvalue reference to allow moving it, but doesn't guarantee a move operation. Constructor, destructor and copy assignment. The std::is_move_assignable template of c++ stl is used to check whether the t is a move assignable type(that can be assigned an rvalue reference of the same type) or not. The standard c++ library gained a function template called std::move, which, despite its name, does not move anything. For efficient transfer of resources from one object to another. This makes me think the error is overflow with accumulate, i'm not sure what the problem could be though. Avoid functions such as create, init, destroy, copy and clone. Asking for help, clarification, or responding to other answers. For example, we can write a more effective version of swap using std::move:
