Definition of various pointers:

1. Integer: int;

2. a pointer to the integer number: int *;

3. a pointer pointing to an integer: int **;

4. An array with 10 integer numbers: int a [10];

5. An array with 10 pointers, each pointing to an integer: int * a [10];

6. a pointer to an array with 10 integer numbers: int (* a) [10];

7. a pointer pointing to an array with 10 integer numbers: int (** a) [10];

8. a pointer to an array with 10 integer pointers: int * (* a) [10];

9. a pointer to a function. The function has an integer parameter and returns an integer number: int (* a) (int );

10. An array with 10 pointers pointing to a function. This function has an integer parameter and returns an integer number: int (* a [10]) (int );

11. A function pointer is a function with two Integer Parameters and returns a function pointer. The returned function pointer points to a function with an integer parameter and returns the integer number: int (* a) (int, int) (int );
