otherwise int *a2={0,1,2,3,4,5,6,7,8,9} a2 is a pointer (and i think you can't initialize it like that), and even if you do a2 = a1 the memory is still 'owned' by a1. You can see that a1 and a2 are different types by using sizeof . a2 is only size of a pointer, while a1 is sizeof(int) * 10
int a[10]={1,2,3,4,5,6,7,8,9,10},*p=a; 则数值为9的表达式是选B记住这样一个无条件相等的等式：*(p+i)与P[i]无条件等价。因为p是指向数组a首元素的地址，所以p[i]又和a[i]等价。易知B选项即为p[8]，也即为a[8]，其
Answer to Consider the array declaration. Your solution's ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.
a is 3D array with size [3][3][3] Therefore each 2D array contains 9 elements, we have 3 such arrays. 0th 2D array have {1,2,3,4,5,6,7,8,9} 1st 2D array have {10,11,12,13,14,15,16,17,18}
Here, p is pointer to 0 th element of the array arr, while ptr is a pointer that points to the whole array arr. The base type of p is int while base type of ptr is 'an array of 5 integers'.; We know that the pointer arithmetic is performed relative to the base size, so if we write ptr++, then the pointer ptr will be shifted forward by 20 bytes.; The following figure shows the pointer p and ...
- Adding 3 to this: *(a + **a + 2) + 3 is the same as taking the fourth row and moving the pointer 3 positions to the right. - *(a + **a + 2) + 3 points to a[3] + 3, i.e., &a[3][3] which is the element a[3][3]. Final Dereferencing - - *(*(a + **a + 2) + 3) is dereferencing the address of a[3][3] , which is 19.
