In a dynamically-sized coarray declaration, the extent of the leading dimension is left unbounded. The size of this extent cannot be part of the template type because it is not known at compile time. Instead, the size is passed as a constructor argument: coarray<int[][20]> y(n);...
Remarks:WhenTis an array type, this constructor shall not participate in overload resolution unless the expressiondelete[] pis well-formed and eitherTisU[N]andY(*)[N]is convertible toT*, orTisU[]andY(*)[]is convertible toT*. ... To support this, the member typeelement_typeis now defined...

Constructors and destructors are fundamental to the concept of classes in C++. Both constructor and destructor are more or less like normal functions (but with some differences) that are provided to enhance the capabilities of a class. Constructor, as the name suggests is used to allocate memory...

What are nameless temporary objects in C++? Sometimes to reduce the code size, we create nameless temporary object of class. When we want to return an object from member function of class without creating an object, for this: we just call the constructor of class a...
TheArgsinnewElementis whatever you would pass to the constructor ofT(magic of C++11 perfect forwarding). For more information, see the reference to [allocator_traits] (http://www.cplusplus.com/reference/memory/allocator_traits/) or the [standard allocator] (http://www.cplusplus.com/reference/...
You can pass a shared_ptr to another function in the following ways:Pass the shared_ptr by value. This invokes the copy constructor, increments the reference count, and makes the callee an owner. There's a small amount of overhead in this operation, which may be significant depending on ...
