Its basically the stars that are at one of the earths axes or stars that point to the main stars at the 2 axes.
The two pointer stars point to Polaris, the north star
Merak and Dubhe, often referred to as the pointer stars, point to Polaris, which many people know as the North Star.
If you spend any time outside at night looking at the stars, you may have noticed that they're constantly moving. The Big Dipper turns completely around the Pole Star every day, almost like the hand of a huge clock. So, if you pick any star at all in the sky, except for the Pole Star itself, the altitude and azimuth of any star you pick are constantly changing.
You get parallax errors with analogue meters if you don't align your eye so that it is perpendicular to the pointer. When this happens the pointer can appear to line up with the wrong mark on the scale. The further your point of view is away from the perpendicular, the greater the error. The potential for errors can be reduced by minimizing the gap between the pointer and the scale or better still fitting a mirror behind the pointer so that it is in the same plane as the scale. The mirror assists the viewer find the correct point of view, since in this condition (correct point of view) the reflection of the pointer will be hidden behind the pointer.

Pointer Stars are stars that are used to pinpoint other areas in the sky, such as constellations.
I do not know which star is the one you refer to as "Pointer Star" but Arcturus has a declination (angle above the celestial equator) of +19° 10′ 56″. If yout "Pointer Star is "Polaris" then the angular distance between these stars is (90° - 19° 10′ 56″) or 70° 49' 04"
It is Polaris.

The double star (**) notation is not specific to initializing a variable in a class. It is simply a double indirect reference to an object.float myFloat; // an objectfloat *myFloatPtr; // a pointer to an objectfloat **myFloatPtrPtr; // a pointer to a pointer to an objectmyFloat = 123.456; // initialize an objectmyFloatPtr = &myFloat; // initialize a pointer to an objectmyFloatPtrPtr = myFloatPtr; // initialize a pointer to a pointer to an objectmyFloat; // refer to an object*myFloatPtr; // refer to an object through a pointer**myFloatPtrPtr; // refer to an object through a pointer to a pointer*myFloatPtrPtr; // refer to the value of the pointer to the objectDouble pointer notation is used where the caller intends that one of its own pointers need to be modified by a function call, so the address of the pointer, instead of the address of the object, is passed to the function.An example might be the use of a linked list. The caller maintains a pointer to the first node. The caller invokes functions to search, add, and remove. If those operations involve adding or deleting the first node, then the caller's pointer has to change, not the .next pointer in any of the nodes, and you need the address of the pointer to do that.
