C - 以下代码中变量的类型定义是什么？

Question

What is the type definition of a variable x in this code?

typedef int *f(int);
f *x;

Answer 1

f is an alias for a function type that takes int as an argument and returns an int* .

As such it isn't particularly useful.

(If you wanted f to be a pointer to a function that takes an int and returns an int , you'd have to write typedef int (*f)(int); )

Answer 2

typedef int* f(int);

type f is function with int parameters and returning pointer to int .

You cannot define a function using a typedef for a function type. please see the stack overflow answer.
