Empty string

An empty string is a string data type that contains no characters. In programming and computer science, it is often represented by a pair of double quotes with nothing in between (`""`) or single quotes (`''`). The length of an empty string is zero, meaning it has no content. Empty strings are commonly used in various contexts, such as: 1. **Initialization**: Setting a variable to an empty string to indicate that it is not yet assigned any meaningful value.
