发帖数: 1930 | 5 i guess you can pre-allocate some memory in compile time, and then manage
that memory yourself (memory pool alloc/free), and then redefine the new
operator (class specific operator new)

发帖数: 335 | 6 There are 3 memory storage types for c++ to allocate memory for an object.
1. stack memory for object inside a function.
2. static storage for namespace-scope objects and local static objects
3. heap storage for dynamically-allocated objects.
If the stack in you problem refers to the first type of memory storage,
there is only one method that you could do this, which is defining a
function, allocating memory for an object inside a function, and using it.
You cannot use it outside of a function.

如果禁止一个对象在stack上生成；把析构函数声明成私有函数
如果只想在heap上生成；构造函数声明成私有；同时提供虚拟构造函数（这里不是指
virtual constructor,而是指用factory patterns生成对象） |

发帖数: 560 | 8 what's your point?
we want to get an object instance on Stack, your methods are reverse?

发帖数: 245 | 9 To prohibit heap-based objects, we can declare operator new (and operator
delete) as private since it is called by the new operator. |
