Pointer array and array pointer

Two-dimensional array: int a [3] [4] = {1, 2, 3, 4}, {5, 6, 7, 8}, {9, 8, 7, 6 }}; pointer array: int * pa [4]; Note: 1. the pointer array is actually an array, but the elements in the array are pointers, in this example, arrays are stored in pa [0], pa [1], pa [2], and pa [3]. 2. assign a value to a two-dimensional array. a single value is required, that is, * pa = a; * (pa + 1) = a [1]; * (pa + 2) = a [2]; * (pa + 3) = a [3]; array pointer: int (* ap) [4]; Note: 1. array pointer is actually a pointer, the Pointer Points to an array. In this example, the pointer points to a one-dimensional array. 2. assign a value to a two-dimensional array. Because int (* ap) [4]; is equivalent to int ap [] [4], you only need ap =.
