A function q that accepts a pointer to a character as argument and returns a pointer to an array of integer can be declared as
| A. | int (*q (char*) )[ ] |
| B. | Int *q(char *)[ ] |
| C. | int (*q) (char *)[ ] |
| D. | none of the above |
|
Option: A Explanation : Function Input : 'Pointer to a character'. For example : Pointer to a character will be represented as "char * Y" which will signify (Y is a pointer to character) Similarly in this case, a general argument notation would be "char *" Function Output : 'Pointer to an array of integers'. For example : Pointer to an array of integers will be represented as "int(*Z)[10]" which will signify (Z is a pointer to an array of integers) Similarly in this case, a general argument notation would be "int(*)[]" Function Name : 'q'. Now, in this case when we combine the input, output and function name, the function representation will becomes int (*q (char*) )[ ] This will hence signify that the function takes an input as pointer to a character and returns pointer to an integer array.
