C pointer to array/array of pointers disambiguation

Question

What is the difference between the following declarations:

int* arr1[8];
int (*arr2)[8];
int *(arr3[8]);

What is the general rule for under

Answer 1

I guess the second declaration is confusing to many. Here's an easy way to understand it.

Lets have an array of integers, i.e. int B[8].

Let's also have a variable A which points to B. Now, value at A is B, i.e. (*A) == B. Hence A points to an array of integers. In your question, arr is similar to A.

Similarly, in int* (*C) [8], C is a pointer to an array of pointers to integer.
