A "string" is a sequence of characters, often used in programming and computer science. It can include letters, numbers, and symbols, and is typically enclosed in quotes. For example, the string "Hello, World!" contains a greeting message. Strings are essential for handling text data, allowing programmers to manipulate and display information easily. In everyday life, we also encounter strings in various forms, such as a piece of yarn or a musical string. Just like in programming, these strings can connect things together or create beautiful sounds. Whether in code or in music, strings play a vital role in communication and expression.
