What would the data type 'char' primarily be used for in C?

• A. For storing whole numbers
• B. For storing floating-point numbers
• C. For storing a single character
• D. For storing arrays of strings

Answer: (C)

The data type 'char' in C is primarily used for storing a single character. This data type is typically one byte in size and is capable of storing alphabetic characters, digits, and other special symbols. In programming, it is essential to represent text as individual characters, and the 'char' type effectively serves this purpose. For example, when you declare a variable of type 'char', such as `char letter = 'A';`, you are allocating space to store the character 'A'. This is fundamental in handling strings and character data within your programs. In contrast, the other options do not align with the primary use of the 'char' data type. Whole numbers are typically stored in types like 'int', floating-point numbers utilize 'float' or 'double', and arrays of strings would be represented using arrays of 'char' or pointers to 'char' arrays, specifically designed to handle multiple characters rather than a single one. Thus, 'char' is the correct choice because it is explicitly designed for single character representation.
