将 make_shared 与 char[] 或 int[] 一起使用
Using make_shared with char[] or int[]
你能告诉我这在 VS2015 中是否有效？
shared_ptr< char> buffer( make_shared< array< char,10>>() , [] (char *p){delete[] p; } );
或
shared_ptr< char> buffer( make_shared< array< int,10>>() ,default_delete< int[]>());
Visual Studio 2015 不支持 C++17 标准。在 C++17 标准之前你不能有 std::shared_ptr<T[]> 指针。但即使在 C++17 中， std::make_shared function doesn't support array types so you would have to use the boost::make_shared instead. Another alternative is to use the unique pointer in combination with the std::make_unique 也支持数组类型。正如 Scot Meyers 在他的“有效
《现代 C++》一书：
The existence of std::unique_ptr for arrays should be of only
intellectual interest to you, because std::array, std::vector, and
std::string are virtually always better data structure choices than
raw arrays.
