答案很短,你可以 t。
You can have a pointer to an object of the same type, but not an object itself.
If you NEED to do this (i.e.) can t use a pointer, your design is probably wrong. If you can use a pointer, use it.

你们不得不在瞬时制造这个物体,这意味着对施工者发出明确的休养呼吁。
物体的<代码>sizeof()是什么?
你可以这样做,因为这样做需要无限期的再次入侵。 (Your t
将包含另外的t
,因此,您有t.t.t.t.t.t.t.t.t.t.t.t.t.t.t. .
ad infinitum. 你可以做些什么是把另一个物体放在内,如内。
private:
Test *t;
问题在于,你写了:
Test t;
编辑的大小。 测试代码>,以便提供足够的储存。 页: 1 测试编号;
:由于汇编者没有看到<代码”定义的结尾,因此,该尺寸为t。 测试代码>(即;
> 封闭式>后,从而可以确定其大小。
That s not possible. At the max you can have a reference or pointer of the same
class
within it.
class Test
{
private:
Test *t;
};
作为附带说明,<代码> static物体获准。 这是因为它们实际上与任何特定的<代码>}/代码>无关。 反对。 i.e:
class Test
{
private:
Test t; // error
static Test st; // ok!
}; // define st in the translation unit
