这两个声明有什么区别 [英] what is the difference between these two declarations

问题描述

int *f()
int (*f)()

推荐答案

int *f();

f 是一个函数，它返回一个指向整数的指针.

f is a function returning a pointer to an integer.

int (*f)();

f 是指向函数的指针(指向函数返回一个整数值).

f is a pointer to a function (pointed function returns an integer value).

第一个将f声明为指向类型的指针的变量int.
第二个将f声明为类型函数的变量，不带任何参数返回int

P.P.S .:我错了，正如CPallini指出的那样，第一个是函数声明.有关说明，请访问本周第一大师 [

The first declares f as a variable of type pointer to int.
The second declares f as a variabvle of type function with no parameters returning an int

P.P.S.: I was wrong, the first is a function declaration, as CPallini pointed out. Explanations can be found at Guru Of The Week #1[^]
