The answer is not appropriate as the function is declared as no return type using parenthesis. if the declaration would been void *cmp(); then this answer might be right. Or else explain the difference between Q10 and Q8 ?

@Saxena. The above answer is correct because here cmp is function pointer, which is pointing to a function which return nothing (void). Since it's correct.

@Amit. Can you explain us why the answer is not appropriate?

Example for cmp is a pointer to a function which returns void: #include<stdio.h> void cmp (void) { printf("Example for Function Pointer"); } int main() { void (*fun_ptr)(void); //Syntax for Function pointer fun_ptr = cmp; fun_ptr(); return 0; }
