What does 'string' represent in programming?

In programming, a 'string' represents a sequence of characters. This can include letters, numbers, symbols, and whitespace, all grouped together. Strings are used to manipulate text and are commonly used for tasks like displaying messages, taking user input, or processing text data.

The concept of a string being a sequence means that you can have multiple characters in a single variable. For example, "Hello, World!" is a string that consists of multiple characters. Strings can be defined in various ways depending on the programming language, such as using quotes or apostrophes to enclose the character sequence.

The other options refer to different types of data. A single character is just one element, which is not the full representation of a string. A numeric value refers to data types that represent numbers, while a boolean value indicates true or false conditions. Thus, the definition of a string as a sequence of characters distinctly highlights its unique role in representing text data in programming.
