![AD选项a[2]为什么会转化为行为指针，而不是他的地址，如果是a[2][1]呢，也会转化为指针类型？](https://file.115kc.com/storage/question/e839e913bf50cf6a0f2576f43020a0f4.png "AD选项a[2]为什么会转化为行为指针，而不是他的地址，如果是a[2][1]呢，也会转化为指针类型？")
![Why is AD option a[2] converted to an action pointer instead of its address, and if it is a[2][1], also converted to a pointer type?](https://file.115kc.com/storage/eg/image475.jpg)
a[2][1] is the value, a[2]+1 is the address of a[2][1]
Because a is a two-dimensional array, the first dimension represents the number of rows, a[2] represents the second row, is the row pointer, Pointer +3 is the pointer offset, and the offset result is still pointer. a[2] is the pointer in the second row, and +3 is the address of three pointer type variables from the first address in the second row to the right, so it is the address of the third element in the second row
