Concatenation (ˈkonˌkatəˈnāSHən), also referred to as stringing together, is a common computer programming concept involving the combining of two or more entities into a single output. Specifically, concatenation is the operation of joining character strings end-to-end. This action combines the characters of the separate strings into a single longer string.
Concatenation is used in many programming languages to join stringsg of characters together. It is widely used to combine multiple words into one sentence, concatenating words from multiple text strings into one long string, such as strings of HTML code, or to join multiple pieces of data into one formatted string. For example, a computer programmer may combine the name “John” and the surname “Smith” into one string, resulting in “John Smith”.
Concatenation is usually done using the “+” operator in most programming languages. For example, in the C programming language, it is done by writing “John” + “Smith”. In Python, it is done using a double slash (//) followed by the word “concatenate”: “John” // “Smith”.
In addition to string concatenation, it can also be used to combine databases, numbers, and other types of data. For example, it can be used to join numbers together, such as 123456, resulting in “12,345,6”.
Concatenation is an important programming concept and is useful for a variety of tasks. It allows for the combining of strings in order to simplify programming tasks. Furthermore, it can be used to join various pieces of data into a single output, making it easier to analyze and manipulate data.
