这个函数的声明

Question

how to explain this right

char*(*a)(int, int);

just explain what does this declaration means. I'm not sure how to explain it right. Thank you very much!

Answer 1

a is a pointer to a function with two parameters of type int that returns a char* .

The ``Clockwise/Spiral Rule''

cdecl: C gibberish ↔ English

Answer 2

像这样： a是一个指向函数的指针，它接受两个int参数并返回指向char指针。

Answer 3

To make this declaration

char*(*a)(int, int);

clear use a typedef. For example

typedef char * FunctionType( int, int );

FunctionType *a;

That is a is a pointer to the function type char * ( int, int ) .
