What is the Char's field?

Many characters in most computer programming languages ​​are commonly known as the Char field. This is mainly because "Char" is keywords in languages ​​such as C, which is used to declare a variable type of scalar characters. The Char Field is a sequence of characters recorded in a long row of consecutive addresses, which can be quickly accessed using the element index in the field. Like many fields of scalar data types, the advantages of using Char fields is to allow quick random access and replacement of values ​​in any positions in the field.

In object -oriented programming languages, such as Java®, it is important to understand that the Char's field represents a sequence of scalar values ​​and not classes or objects. The scalar data type is the one that is stored only as a piece of date, such as the integer. This is unlike a number of character objects that contain methods and possibly other support variables, such as serializinformation on synchronization.

The character in most computer languages ​​is a data type designed to hold a single letter or symbol because it is represented by encoding characters used by a program or operating system. For this reason, with the exception of strongly standardized languages, the actual size of the character in memory may be different in each system. This information may change when trying to browse the Charfish field using the indicator arithmetic, where instead of using simple increment operators and reducing the indicator calculations, the character size defined must be used by the system. Relying on the field in which the size of the character 1 byte or 2 bytes can cause unpredictable behavior and errors if the program is lowered on another system in which the character can be defined differently.

Within some programs, it was possible to use a number of characters as a basis for implementation of a string class or an advanced string type. In the C programming language, the strings are actually processed in a way thatIt is very similar to the Chaar Field, in which the sequences of the characters are for forming a string and informing the program that the string ended with a zero character. The class of its own chain could be designed to mimic this behavior using the field.

Other uses for the Char's fields include compression or coding types that do not necessarily have to be based on octares, but on human readable features. The field could also serve as a type of buffer for processing longer text blocks that are held in the physical media file, or those read from the network socket. Most of the features for which the Char fields are used include text input and output simply because the size of the scalar character is unpredictable from one system and a compiler for the other in many languages, so it is not possible to rely on the holding of the integer values ​​beyond a certain range.
