What is the difference between them?

int **a[10];
int *(*a)[10];
int (*a[10])();

> int **a[10];

declare a as array 10 of pointer to pointer to int

> int *(*a)[10];

declare a as array 10 of pointer to pointer to int

> int (*a[10])();

declare a as array 10 of pointer to function returning int

cdecl is your friend.

int **a[10];

declare a as array 10 of pointer to pointer to int

int *(*a)[10];

declare a as array 10 of pointer to pointer to int

int **a[10];

declare a as array 10 of pointer to pointer to int

int *(*a)[10];

declare a as array 10 of pointer to pointer to int

int (*a[10])();

declare a as array 10 of pointer to function returning int

cdecl is your friend.

cdecl is indeed a great tool. It is discussed in K&R. The man page for
it is really kewl as it contains examples, grammar etc.

But I was wondering if there is a systematic method to do it yourself.
I mean a step by step human understandable approach

good answer!

Terrible answer. It was top-posted, losing all connection with the
actual problem. Your answer belongs after the material to which
you reply, after snipping anything immaterial.
