C++ for Beginners - Simple Data Type: bool

The video tutorial introduces the Boolean data type, named after George Boole, which holds true or false values. It demonstrates practical applications in programming, such as using Boolean variables in if statements to control program flow. The tutorial explores various methods to assign Boolean values, including using numbers and expressions. It concludes with a summary of Boolean variables' role in decision-making processes.
