Using SBRM, we can rely on classes which handle their own resource management. Instead of worrying about obtaining and releasing underlying resources, we are able to focus on the higher level logic.
WebThe above is an example of an RAII class where the resource is an array of 100 integers. It could as well be a file handle, network socket, or an object which pushes an object onto a std::stack when it is constructed and pops it from the std::stack when it is destroyed. UnicycleBloke • 4 yr. ago
