Experience:

Recursion 的問題:

• unbound argument.


• stack maintain difficult.

Task vs Function

• Tasks can't return value


• Function can return value.


• task do_this( input int data=0, addr=0, ctrl=2 ), default arguments :


• for example: do_this(5,2 ) 、do_this( ,,0), do_this( .data(5), .addr(2) );


• const ref let argument Readonly.

雜項:

1. automaic 函式結束記憶體隨即釋放, 節省記憶體使用.


2. void 表不回傳值, 省空間only.


3. static 用法同C.


4. ref ( call by reference ) 有點不相同, 不過更簡單, **問題已經幫你處理好了.
