The control structures of Go are related to those of C but differ in important ways. There is no do or while loop, only a slightly generalized for; switch is more flexible; if and switch accept an optional initialization statement like that of for; break and continue statements take an ...
If we change the type off’s parameter fromT&toconstT&, things change a little, but not in any really surprising ways. Theconstness ofcxandrxcontinues to be respected, but because we’re now assuming thatparamis a reference-to-const, there’s no longer a need forconstto be deduced as...
Early sections on creating and destroying objects show you ways to make better use of resources, including how to avoid duplicate objects. Next comes an absolutely indispensable guide to implementing "required" methods for custom classes. This material will help you write new classes that cooperate ...
Item 17: Store newed objects in smart pointers in standalone statements. Designs and Declarations Item 18: Make interfaces easy to use correctly and hard to use incorrectly. Item 19: Treat class design as type design. Item 20: Prefer pass-by-reference-to-const to pass-by- value. 参考文档...
Item 20: Use std::weak_ptr for std::shared_ptr-like pointers that can dangle. Item 21: Prefer std::make_unique and std::make_shared to direct use of new. Item 22: When using the Pimpl Idiom, define special member functions in the implementation file. ...
