int arr[]= {5,15,1,3,4};
// Since we know arr and &arr are both address of first element of array.
// I read somewhere that &arr+1 = baseaddress + sizeof(arr).
// arr+1 = address of second element
// am curious to know the diff. between two semantics.
printf("%d %d\n",*(arr+1), *(&arr+1));
我知道这很简单,但我很想弄清楚这个概念。
