operator-> is used to access members through a pointer:


class obj
{
public:
int member;
}

int main()
{
obj *object = new obj();
//access member of object
object->member = 1;
delete object;
return 0;
}





Similarly, you could dereference the pointer and use operator.:
(*object).member = 1;

And no, <- is not a valid operator.

"->" Is use to access an element of a class or struct via a pointer.

For example:


struct foo{
int a;
};

...

foo* f = new foo;

// You can write:
foo->a = 10;
// Or you can write:
(*foo).a = 10;




And to your second question, no you cannot reverse the arrow.
