@All.
The eg Syntax is;
struct node
{
int data;
};
main(){
struct node p,*a;
P.data=10;
a=&p;
printf(" %d",a->data);
}
And Output is 10.

I think the answer given to the question is wrong.
We can use(*p).x instead of using ->.

We can use either (*p).x or p->x where x is the member of the structure.

Here we can use arrow operator to access structure members without creating structure variable that's why we used -> (arrow) operator.

Because it is a De-reference operator (->). So the data members can easily accessible.

When ever we want to fetch the value out of a pointer variable which is store in a structure.
We always use -> (arrow) pointer.
On the other hand if in a structure we have a simple variable of any data type we will use .(dot) operator to fetch the value from a variable.
