(1) int *p;
// p is a pointer to an integer quantity

(2) int *p[10];
// p is a 10-element array of pointers to integer quantities

(3) int (*p)[10];
// p is a pointer to a 10-element integer array

(4) int *p(void);
// p is a function that returns a pointer to an integer quantity

(5) int p(char *a);
// p is a function that accepts an argument which is a pointer to a character returns an
// integer quantity
