(1)

Code:

int *p;

// p is a pointer to an integer quantity

(2)

Code:

int *p[10];

// p is a 10-element array of pointers to integer quantities

(3)

Code:

int (*p)[10];

// p is a pointer to a 10-element integer array

(4)

Code:

int *p(void);

// p is a function that returns a pointer to an integer quantity

(5)

Code:

int p(char *a);

// p is a function that accepts an argument which is a pointer to a
character returns an
// integer quantity

(6)

Code:

int *p(char *a);

// p is a function that accepts an argument which is a pointer to a
character returns a
// pointer to an integer quantity

(7)

Code:

int (*p)(char *a);

// p is pointer to a function that accepts an argument which is a pointer to
a character
// returns an integer quantity

(8)

Code:

int (*p(char *a))[10];

// p is a function that accepts an argument which is a pointer to a
character returns a
// pointer to a 10-element integer array

(9)

Code:

int p(char (*a)[]);

// p is a function that accepts an argument which is a pointer to a
character array returns
// an integer quantity

(10)

Code:

int p(char *a[]);

// p is a function that accepts an argument which is a array of pointers to
characters
// returns an integer quantity

(11)

Code:

int *p(char a[]);

// p is a function that accepts an argument which is a character array
returns a pointer to
// to an integer quantity

(12)

Code:

int *p(char (*a)[]);

// p is a function that accepts an argument which is a pointer to a
character array returns a
// pointer to an integer quantity

(13)

Code:

int *p(char *a[]);

// p is a function that accepts an argument which is an array of pointers to
characters
// returns a pointer to an integer quantity

(14)

Code:

int (*p)(char (*a)[]);

// p is pointer to a function that accepts an argument which is a pointer to
a character array
// returns an integer quantity

(15)

Code:

int *(*p)(char (*a)[]);

// p is pointer to a function that accepts an argument which is a pointer to
a character array
// returns a pointer to an integer quantity

(16)

Code:

int *(*p)(char *a[]);

// p is pointer to a function that accepts an argument which is a array of
pointers to
// characters returns a pointer to an integer quantity

(17)

Code:

int (*p[10])(void);

// p is 10-element array of pointers to functions; each function returns an
integer quantity

(18)

Code:

int (*p[10])(char a);

// p is 10-element array of pointers to functions; each function accepts an
argument which is
// a character and returns an integer quantity

(19)

Code:

int *(*p[10])(char a);

// p is 10-element array of pointers to functions; each function accepts an
argument which is
// a character and returns a pointer to an integer quantity

(20)

Code:

int *(*p[10])(char *a);

// p is 10-element array of pointers to functions; each function accepts an
argument which is
// a pointer to a character and returns a pointer to an integer quantity
