对变量、函数和结构/枚举使用doxygen支持的文档样式经常使用\作为doxygen，不要使用@始终使用5x4空格(5个制表符)作为文本行开始的偏移量/** * \brief Holds pointer to first entry in linked list * Beginning of this text is 5 tabs (20 spaces) from beginning of line */statictype_t* list;每个...
of the array includes the null terminator element. An nt_checked array with size d converts to an nt_array_ptr with a count of d - 1 elements. So it should be illegal to declare an nt_checked array with an empty initializer list. ...
when there is just one expression in the initializer list, remove the braces from it. f(3); } 这一新行为会导致重载解决方法要考虑比以往候选更适合的其他候选时,调用将明确地解析为新候选,导致程序行为的更改可能与程序员的需要有所不同。 示例2:重载解决方法的更改(之前) C++ 复制 // In ...
Lst1.assign() 给list赋值 Lst1.back() 返回最后一个元素 Lst1.begin() 返回指向第一个元素的迭代器 Lst1.clear() 删除所有元素 Lst1.empty() 如果list是空的则返回true Lst1.end() 返回末尾的迭代器 Lst1.erase() 删除一个元素 Lst1.front() 返回第一个元素 Lst1.get_allocator() 返...
weak_ptr 允许你共享但不拥有某对象,一旦最末一个拥有该对象的智能指针失去了所有权,任何 weak_ptr 都会自动成空(empty)。因此,在 default 和 copy 构造函数之外,weak_ptr 只提供 “接受一个 shared_ptr” 的构造函数。 可打破环状引用(cycles of references,两个其实已经没有被使用的对象彼此互指,使之看似还...
定位new(placement new)允许我们向 new 传递额外的参数。new (palce_address) type new (palce_address) type (initializers) new (palce_address) type [size] new (palce_address) type [size] { braced initializer list }palce_address 是个指针 initializers 提供一个(可能为空的)以逗号分隔的初始值列表...
The initialization context for an empty braced-initializer-list is copy-initialization, which doesn't allow calls to explicit constructors. There also may be runtime differences, because use of {} to initialize may call a constructor that takes a std::initializer_list, instead of the default ...
