int* arr1[8] and int *(arr3[8]) are same and it means that it will create a pointer array of size 8, i.e. instead of normal array of integers it will be array of pointers and it can store 8 addresses of integer variables. as for the second syntax int (*arr2)[8] defines a pointer to an array: int b[8]; int (*arr2)[8] = &b; now arr2 will have the same values as that of b.

First and third are same result and defined pointer to an array. But in second declaration you defined an array of pointers
