C Booleans

C programming language does not have a built-in boolean data type like some other programming languages. However, C provides support for boolean values using standard C library macros defined in the stdbool.h header file.

The stdbool.h header file defines two macros that can be used to represent boolean values:

1. bool: This macro represents a boolean value and can have two possible values: true or false. In C programming language, true is defined as 1, and false is defined as 0.

2. true and false: These macros represent the boolean values true and false, respectively.

Example:

#include <stdbool.h>
#include <stdio.h>

int main() {
    bool a = true;
    bool b = false;
    
    if (a) {
        printf("a is true\n");
    }
    if (!b) {
        printf("b is false\n");
    }
    
    return 0;
}

In the above example, we have included the stdbool.h header file and declared two boolean variables a and b. We have also used the if statement to check the boolean values of a and b.

Note that in C programming language, any non-zero value is considered true, and 0 is considered false. However, it is good practice to use the true and false macros to make the code more readable and maintainable.
