What are boolean variables?

Boolean variables are data types that can hold one of two possible values: True or False. They are fundamental in programming for making decisions and controlling the flow of a program through conditional statements (like if statements).

Key Points:

• Declaration: In many programming languages, you declare a boolean variable using a keyword (e.g., bool in C++ or simply assigning True/False in Python).
• Usage: Commonly used in conditions to determine the execution of code blocks.
• Operations: You can perform logical operations on boolean variables, such as:
  • AND (&&): True if both operands are true.
  • OR (||): True if at least one operand is true.
  • NOT (!): Inverts the boolean value.

Example in Python:

is_student = True
has_passed_exam = False
can_enroll = is_student and has_passed_exam  # Evaluates to False
