穆兄,我劝你用malloc分配内存,看看我的答案说差4个字节是不是正确的,如果是正确的就说明了我说 new 是默认调用 operator new,而 operator new 是缺省调用  malloc 是正确的

穆扬,

I think it can be so, when you really want know the reality, please ask me all your questions about pointer. And I will answer you. And now the other please stop answering any quetion from 穆扬.

When you have still some else meaning , then we can discuss continue. How do you think about it?

好罗,跟kai大哥学东西

我退出这个讨论,已经弄清楚指针的误会原因了

the pointer is really not simple, but also not difficute. The essenture of Pointer is an address of a allocated space. The allocated space can be just an unit place for some date tpye.

for example

int * a = new int; 4 Byte place will be dynamicaly allocated, and then assign the address to the pointer variable a.

and a block space can also be allocated, for example

int * a = new int[5]; 20Byte will be allocated and then assign the first address of this allocation to the pointer variable a.

穆扬,
