BOOLEAN EXPRESSION Meaning and
Definition
-
A Boolean expression refers to a logical statement or comparison that evaluates to either true or false. It is an essential concept in computer programming and is used extensively in conditions and decision-making processes.
A Boolean expression typically includes one or more variables, constants, and logical operators. Variables represent values that can change, while constants are fixed values. Logical operators, such as AND, OR, and NOT, govern the relationship between variables, allowing for complex evaluations.
The evaluation of a Boolean expression is based on the principles of Boolean algebra. The result can only be one of two possible values – true or false. This evaluation depends on the current values of the variables involved and the logical operations applied.
Boolean expressions are commonly used in programming languages to control the flow of execution. They are crucial in conditional statements like IF-ELSE and WHILE loops to determine whether specific blocks of code should be executed based on the evaluation of the expression.
Boolean expressions are also employed in more complex scenarios, including mathematical equations, search algorithms, and database queries. They help in filtering data, making decisions based on conditions, and implementing various control structures.
In summary, a Boolean expression is a logical statement that evaluates to either true or false. It plays a fundamental role in programming and is used to control execution flow, make decisions, and implement various algorithms. Understanding Boolean expressions is crucial for writing efficient and effective code.

Etymology of BOOLEAN EXPRESSION
The word "boolean" is derived from the name of the British mathematician and logician George Boole, who is known for his work in mathematical logic. The term "Boolean expression" refers to an expression or statement in a programming language that can be evaluated as either true or false. It is named after George Boole's contributions to the field of logic, particularly his development of Boolean algebra, which is a mathematical system that deals with truth values and logical operations.
