1. An array pointer (also called a row pointer): A pointer to an array.

Expression: Int (*p) [n]

Description: First P is a pointer, p points to an array of dimension n, and the elements in the array are integers, so p is a pointer to an array with n integers.

2, pointer Array (also known as the column pointer): that is used to store pointers to the array, that is, the array elements are pointers.
