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;
}
#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;
}

Can you explain us why the answer is not appropriate?

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.

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 ?
