What is a string in programming?

• A. A single character
• B. A numeric value
• C. A sequence of characters
• D. A binary flag

Answer: (C)

Strings represent text by storing a sequence of characters. This means a string can be a word, a sentence, or even the empty string. A single character is its own type, not a string. A numeric value is a number, used for calculations. A binary flag is a boolean, true or false, used to indicate a condition. Strings support useful operations like measuring their length, accessing a character by position, and concatenating multiple strings. In many languages, a string is a distinct data type or class, and while some implementations store strings as arrays of characters, the core idea is that a string is a sequence of characters used to represent text.
