What values can boolean variables hold?

Short Answer

Expert verified
Answer: Boolean variables can hold only two values: True and False. True represents something that is correct or valid, while False represents something that is incorrect or invalid. These values are used in programming for logical operations and conditional statements to determine the validity or correctness of a given condition.

Step by step solution

01

Introduction to Boolean variables

Boolean variables are a data type in programming languages that can only hold two possible values. These values represent either true or false - and they are most commonly used in logical operations and conditional statements. Now, let's explore the two values a Boolean variable can hold.
02

Value 1: True

The first value that a Boolean variable can hold is "True." In programming, True (often represented by the integer 1) represents something that is correct or valid. For example, if we are comparing two numbers, and our logic is to test if one number is greater than the other, if the condition is met, the Boolean variable will hold the value True.
03

Value 2: False

The second value that a Boolean variable can hold is "False." In programming, False (often represented by the integer 0) represents something that is incorrect or invalid. Using the same example of comparing two numbers, if one number is not greater than the other, the Boolean variable will hold the value False. In conclusion, Boolean variables can hold only two values: True and False. These values are used in programming for logical operations and conditional statements to determine the validity or correctness of a given condition.
