An inductive summary of pointer arrays, array pointers, pointer functions, function pointers

an array of pointers , such as int *p[4]: Indicates that a one-dimensional array holds three pointer variables, respectively, p[0], p[1], p[2], p[3], and by default the three pointer variables are all pointing to null, so assign values separately.

Array pointers: such as int (*P) [4]: Indicates that an array pointer is defined, pointing to a one-dimensional array with 4 elements.

pointer functions: such as int *p (): Declares a function p, which returns a pointer of type int.

function pointers: such as int (*p) (): The function pointer is essentially a pointer to the entry address of the function

The best way to discriminate is to look at "*", Brackets put "*" is the XX pointer
