Its basically the stars that are at one of the earths axes or stars that point to the main stars at the 2 axes.
Merak and Dubhe, often referred to as the pointer stars, point to Polaris, which many people know as the North Star.
The pointer stars in the Big Dipper point towards the North Star, also known as Polaris. Polaris is located directly above the North Pole and remains nearly stationary in the sky. This makes it a useful navigational tool for finding north.
The constellation Perseus is not considered a pointer constellation. Pointer constellations, like the Big Dipper and Cassiopeia, help locate other stars or constellations in the night sky. In contrast, Perseus is primarily known for its own notable features, such as the Andromeda Galaxy and the variable star Algol, rather than guiding observers to other stars.
The pointer on a sundial is called a gnomon. It casts a shadow on the sundial face to indicate the time.
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.

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.
The constellation that contains the pointer star for Aries is Pisces. The star Al Rescha, located at the intersection of the two "fish" in Pisces, serves as a guide to locating Aries. Aries itself is represented by the ram and is situated adjacent to Pisces in the night sky.
