How are boolean values represented in C?

In C, boolean values are typically represented using the stdbool.h header, which defines the bool type. The bool type can hold two values: true and false. Here’s how you can use boolean values in C:

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

int main() {
    bool isTrue = true;
    bool isFalse = false;

    if (isTrue) {
        printf("This is true!\n");
    }

    if (!isFalse) {
        printf("This is false!\n");
    }

    return 0;
}

In this example:

• true is defined as 1, and false is defined as 0.
• The stdbool.h header allows you to use the bool type and the true and false constants.
