Step-by-step explanation:
In computer programming, a string refers to a set or sequence of characters that are treated as a single data type. A string can consist of letters, numbers, symbols, and white spaces, and it is often used to represent textual data such as names, addresses, and messages.
Strings are usually enclosed in quotation marks (either single or double) to signify that they are a sequence of characters rather than a mathematical value.
Programs use strings extensively to process text data, search for specific patterns within text, and manipulate or modify the structure of the text. They are also used for input and output operations, such as reading and writing files, displaying messages to users, and communicating with databases or web services.
In short, string is a fundamental concept in computer programming and is used to represent textual data in a usable and manipulable way.
