int (p) (char (a) []);	p is a pointer to a function	as argument as pointer to a character array	an integer
int (p) (char (*a) []);	p is a pointer to a function	an argument as pointer to a character array	a pointer to an integer
int (p) (char *a []);	p is a pointer to a function	an argument as array of pointers to characters	a pointer to an integer
int (*p [10]) ();	p is a 10 element array of pointers	to functions	each function returns an integer
int (*p [10]) (char a);	p is a 10 element array of pointers to functions	each functions takes an argument as character	an integer
int (p [10]) (char a);	p is a 10 element array of pointers to functions	each function takes an argument as character	a pointer to an integer
int (p [10]) (char *a);	p is a 10 element array of pointers to functions	each function takes an argument as pointer to a character	a pointer to an integer

These are explained as following below.

p is a pointer to an integer.
```
int *p;  
```

```
int (*p)[10];  
```
p is a function that returns a pointer to an integer.
```
int *p();  
```
p is a function that takes an argument as pointer to a character and returns an integer.
```
int p(char *a);  
```
p is a function that takes an argument as pointer to a character and returns a pointer to an integer.
```
int *(char *a);  
```
p is a pointer to a function that takes as argument as pointer to a character and returns an integer.
```
int (*p) (char *a);  
```
p is a function that takes an argument as pointer to a character and returns a pointer to a 10 element integer array.
```

```
p is a pointer to a function that takes an argument as array of pointers to characters and returns a pointer to an integer.
```
int *(*p) (char *a []);  
```
p is a 10 element array of pointers to functions, each function returns an integer.
```
int (*p [10]) ();  
```
p is a 10 element array of pointers to functions each functions takes an argument as character, and returns an integer.
```
