strängliteral

A strängliteral, or string literal, is a sequence of characters enclosed within quotation marks, used in programming languages to represent text. These characters can include letters, numbers, punctuation, and special symbols. The specific type of quotation mark used can vary between programming languages, with common choices being single quotes (e.g., 'hello') and double quotes (e.g., "world").

String literals are fundamental data types used for storing and manipulating text data. They can be assigned to variables, passed as arguments to functions, and used in various string operations such as concatenation (joining strings together), comparison, and searching.

The characters within a string literal are typically interpreted literally, meaning that each character is treated as its intended value. However, some characters may require special handling, often through escape sequences. For example, to represent a double quote character within a double-quoted string, one might use a backslash preceding the quote (e.g., "He said, \"Hello!\""). Similarly, newline characters or tab spaces are often represented by escape sequences like \n and \t, respectively. The exact set of supported escape sequences and their behavior can differ depending on the programming language. Understanding how to correctly use and interpret string literals is crucial for effective text processing and data handling in software development.
