Question 1: (& A) gets an array pointer such as int(*)[5]. Then + 1 skips the whole array and points to the position after 5. *(a+1)=a[1]=2;    * (ptr-1) = skip an element to point to 5 int main(){ int a[5] = { 1, 2, 3, 4, 5 }; int* ptr = (int*)(&a + 1); printf("%d,%d", *(a + 1), *(ptr - 1));   Question 2: 1.
