Boolean:

In C, the boolean data type is not explicitly defined. However, it is common practice to use the _Bool data type or include the stdbool.h header to use the bool type for boolean values. In this example, I’ll demonstrate using the stdbool.h header.

Example:

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

int main() {
    // Declaration and initialization of boolean variables
    bool isSunny = true;

    // Using if-else statement with boolean condition
    if (isSunny) {
        printf(“It’s a sunny day!n”);
    } else {
        printf(“It’s not sunny today.n”);
    }

    return 0;
}

 

Output:

It’s a sunny day!

Explanation of code:

• #include <stdio.h>: This line includes the standard input-output library for functions like printf.
• #include <stdbool.h>: This line includes the standard boolean library, which provides the bool type.
• int main(): The main function, where the program execution begins.
• bool isSunny = true;: Declaration and initialization of a boolean variable.
• if (isSunny) { … }: The if statement checks if isSunny is true.
• printf(“It’s a sunny day!n”);: If isSunny is true, this message is printed.
• else { … }: If isSunny is false, the code inside the else block is executed.
• printf(“It’s not sunny today.n”);: If isSunny is false, this message is printed.
• return 0;: Indicates successful program execution.
