a引用就像一个别名。同一事物的不同名称（即

对象或函数）。指针指向

变量/对象的物理地址。

添加到Oliver帖子，应始终初始化参考，

指针不需要。


他们又有许多优点和缺点......书中更多内容

Hi,

a reference is like an alias. A different name for the same thing (i.e.
object or function). A Pointer points to the physical address of a
variable/object.

Adding to Oliver post, refferences should always be initialised,
pointer need not be.

they again have many adavantages and disadvantages...more given in book
