pointer
pointer, breed of large sporting dogsporting dog, classification used by breeders and kennel clubs to designate dogs bred for pointing, flushing, and retrieving game. These dogs hunt by air scent—as opposed to most hounds, which are ground scenters—and their quarry is primarily game birds. .....

Its short, dense, shiny coat may be solid liver, black, yellow, or orange, or, more frequently, white with any of these colors as markings. The pointer is a scent hunter used for upland game birds. Having located its quarry, it stands rigidly poised with its body and nose facing the game, thus directing the hunter to it. Bred from crosses of foxhound, greyhound, and bloodhound with an early "setting" spaniel, the pointer was originally used to find and point hares, which were then chased and killed by greyhounds. With the rise in popularity of wing-shooting in the early 1700s, the pointer quickly became regarded as an expert gundog, a reputation it continues to enjoy today. The term pointer is also widely used to designate a dog of any breed that characteristically points its quarry. See dogdog, carnivorous, domesticated wolf (Canis lupus familiaris) of the family Canidae, to which the jackal and fox also belong. The family Canidae is sometimes referred to as the dog family, and its characteristics, e.g. .....

Pointers were introduced into Russia in the 1860’s. The dogs stand up to 63–65 cm high and have a retangular muzzle, drooping ears, and a whiplike tail. The coat may be black, pale yellow, brown (sometimes with white spots), or white with black, yellow, or brown spots and speckles. Pointers have a keen sense of smell and are able to point for a long time in front of their quarry. The dogs are used for hunting swamp, steppe, and forest birds.

A pointer may be typed, with its typeindicating the type of data to which it points.
The terms "pointer" and "reference" are generallyinterchangable although particular programming languages oftendifferentiate these two in subtle ways. For example, Perlalways calls them references, never pointers. Conversely, inC, "pointer" is used, although "a reference" is often used todenote the concept that a pointer implements.
Anthony Hoare once said:
Pointers are like jumps, leading wildly from one part of thedata structure to another. Their introduction into high-levellanguages has been a step backward from which we may neverrecover.
