ct answerIn C, which data type is used to store true/false values?Optionsintcharboolboolean

Break Down the Problem

1. Identify the data types available in C.
2. Determine which data type is specifically used for boolean values.

Relevant Concepts

• In C, various data types include int, char, and bool.
• Prior to the C99 standard, C did not have a built-in boolean type. Instead, integers were often used, where 0 represents false and any non-zero value represents true.
• The C99 standard introduced the bool data type, defined in the <stdbool.h> header file.

Analysis and Detail

1. Options Provided:

   • int: Generally used for integer values. Not suitable for true/false.
   • char: Used for character data, can represent 'true' or 'false' as characters but not as logical values directly.
   • bool: Introduced in C99 as a built-in type to represent boolean values (true/false).
   • boolean: Not a standard type in C.

2. Conclusion:

   • The correct choice for representing true/false values in modern C (C99 and onward) is the bool data type.

Verify and Summarize

• The introduced stdbool.h header allows use of bool, true, and false.

Final Answer

The correct answer is bool.
