 developed in England more than 300 years ago. It stands between 23 and 26 in. (58.4–66.4 cm) high at the shoulder and weighs between 50 and 60 lb (22.7–27.2 kg). 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.

Pointer

 

a breed of short-haired hunting dog, developed in England by crossing a Spanish Pointer with an English Foxhound. 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.

pointer

(programming)
An address, from the point of view of a programming language. A pointer may be typed, with its type indicating the type of data to which it points.

The terms "pointer" and "reference" are generally interchangable although particular programming languages often differentiate these two in subtle ways. For example, Perl always calls them references, never pointers. Conversely, in C, "pointer" is used, although "a reference" is often used to denote the concept that a pointer implements.

Anthony Hoare once said:

Pointers are like jumps, leading wildly from one part of the data structure to another. Their introduction into high-level languages has been a step backward from which we may never recover.

pointer

(1) In database management, an address embedded within the data that specifies the location of data in another record or file.

(2) In programming, a variable that holds the address of another variable or the address of the beginning of an array of variables. When a pointer to an array is used, it is made to point to any element in the array by incrementing or decrementing its contents (incrementing or decrementing the address). See subscript.

(3) A symbol used to point to some element on screen. See cursor.

(4) See symbolic link and redirection.
