They never go out of style. Some people are fascinated and try to create them, while others lament their natural existence and try to eliminate them when they spread throughout their entire hair. We are talking about the loops, those curlers or curls that form in the hair and that give a very particular appearance.
For example: “When I was little, my head was full of loops”, “The model surprised to change her look and abandon the loops”, “A loop fell right between her eyes, giving her a very nice appearance”.
The loop concept, however, can also be used in other areas. Different elements that have a kinky appearance, similar to a helicoid, can be mentioned as a loop. It is even possible to refer to loops that are named for their operation and not for their appearance.
In the field of programming, a loop is a structure that allows the repetition of sentences many times. When the programmer stipulates a certain condition and that condition is met (that is, it is true), the execution of the loop occurs, which will only stop when the condition is no longer met.
What is the advantage of including a loop in the schedule? This type of structure allows an action to be repeated over and over again, without the need to copy identical code. This way, the final code is cleaner and can be modified more easily.
According to DigoPaul, the loop is not only convenient in certain cases, but is mandatory in others. Today, thanks to advances in technology, video games usually include various types of particles, which are small graphic objects used to simulate water, fire, sand, earth and magic effects, among other things that were formerly animated by hand and they couldn’t dynamically interact with the rest of the objects.
In most cases, especially in products that pursue realism, several hundred particles or more are needed to move and react to events in their environment individually; if a loop were not used to control them, the same code would have to be repeated for each of them, something that no one in their right mind would do. The particle example, while only the most knowledgeable programmers are in the field of creating special effects and simulating elements, is well suited to understanding the utility and potential complexity of a loop.
Although a scene has thousands of water particles, for example, each one with its own life cycle, experiencing different things and adopting different aspects and sizes, it should not be forgotten that they all start from the same class, the same type of object, so they share properties and functions. In other words, if they are all instances of a class called “water”, then they will have the same possibilities and the same “capabilities”, their behavior will be based on the same code, even though the results are different each time.
A loop in which a large group of particles is controlled offers each one the same functions, the same lines of code; However, depending on the state in which each one is, they will travel one way or another within the loop, and that is why it is likely that some will evaporate, others will soak a character’s clothes and others, for example, will spread on the grass. This shows that although a loop can do the same thing in each turn, within it there can be direct or indirect conditions that multiply the possibilities.
For telecommunications, a subscriber loop (also known as a local loop) is the section of a cable run that connects the telephone exchange to the home of the person using the service.
