Employee Dave created In Delegating Constructor. Employee Dave created 补充: 构造函数名=default:让编译器生成默认的某构造函数。 构造函数名=delete:让编译器禁止调用某构造函数。 八,参考阅读 《C++新经典》 《C++ Primer》 《C++ Primer Plus》 C++ Constructors: Types and Copy Constructors (programiz....
Defaulted or deleted trivial copy and move constructors respect access specifiers Previous versions of the compiler did not check the access specifier of defaulted or deleted trivial copy and move constructors before allowing them to be called. This old behavior was incorrect and doesn't conform to...

Copy and move constructors should not be made explicit because they do not perform conversions. Explicit copy/move constructors make passing and returning by value difficult. 拷贝和移动构造函数不应该定义为explicit,应为那样就不会执行类型转换了。显式拷贝/移动构造函数使通过值传递参数和返回结果变得困难...

Iterator debugging and std::move_iteratorThe iterator debugging feature has been taught to properly unwrap std::move_iterator. For example, std::copy(std::move_iterator<std::vector<int>::iterator>, std::move_iterator<std::vector<int>::iterator>, int*) can now engage the memcpy fast path...
