4.A function 'q' that accepts a pointer to a character as argument and returns a pointer..

Answer / garima singh

EVERY ONE HERE IS WRONG...I HAVE READ SOME NOTES AND GOT THE
OPTION 'A' AS CORRECT...
THERE ARE SEVERAL DIFFERENT USES OF POINTERS IN C...THEY ARE
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
(6) 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) 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) 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) 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) 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) 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) 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) 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) 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) 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) 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) int (*p[10])(void);
// p is 10-element array of pointers to functions; each
function

returns
an integer quantity
(18) 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) 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) 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
SO,ACCORDING TO NUMBER 8...OPTION A IS CORRECT!!!
