Which data type is used to store a single textual character?

• A. Strings
• B. Numbers
• C. Char
• D. Boolean

Answer: (C)

When you need to store a single textual character, you use a data type that represents exactly one code point. This type is designed for exactly one character, not a sequence. That’s why it’s the right choice here. Strings, by contrast, are sequences of characters and can hold many characters—words or sentences. Booleans store true or false, and numeric types store numbers, not characters. In many languages this single-character type is called a char and it holds one code point from an encoding like ASCII or Unicode.
