Array of structures and pointer arithmetic

How can I access arrays of structures using pointer arithmetic?

Suppose I have a structure

struct point{
int x;
int y;
}collection[100];

Suppose I have a function

int func(struct point *collection,int size)   

Inside this function, I access the element as shown below.

collection[0].x 

Is it the same as *(collection + 0).x? Since the operator .has a higher priority than the operator *, the collection pointer is first incremented by 0, and the point operator is applied, and then the pointer is played? One way or another, it does not make sense; any refinement is appreciated.
