这个定义如何解释啊

[vcgaoshou]

Node是一个结构， Node *(*fa(int))()怎么描述啊

[HelloDan]

Node *(*fa(int))()

*fa(int) 函数指针
Node *(*fa(int))() 函数，返回值为Node的指针。

[paidfighting]

见到过，如下：

fa是有一个整型参数的函数，其返回值是指针，该指针是指向无参函数的指针，而该无参函数的返回值是指向Node类的指针

很拗口，也不知道出题的人想干什么。。。

[HelloDan]

fa is a pointer to function that has an argument of int,
and the function return a pointer to a function that has no argument and it return Node *

[HelloDan]

fa is a pointer to function that has an argument of int,
and the function returns a pointer to a function that has no argument and it returns a pointer of Node
