What is a boolean value?

A boolean value is a fundamental data type in programming that can have one of two possible values: True or False. This binary nature is essential for logical operations and decision-making processes within code. Boolean values are often utilized in conditional statements, such as if-else structures, allowing the program to execute certain blocks of code based on whether a condition holds true or not. Because boolean values are central to creating logical expressions and controlling program flow, understanding them is crucial for effective programming and algorithm development.

Other options, such as variable types for strings, loop types, and function types returning multiple values, represent different concepts in programming and do not pertain to the definition of a boolean value.
