Boolean Operations

Boolean Operations

Introduction

• Boolean Operations are logical operations that involve boolean variables. They return a boolean value (True or False) after performing a logical computation.

AND Operator

• The AND Operator is a binary operation, meaning it requires two boolean values.
• It returns ‘True’ only if both of its operands (the values being operated on) are ‘True’, otherwise, it returns ‘False’.

OR Operator

• Like the AND Operator, the OR Operator is a binary operation.
• It returns ‘True’ if either or both of its operands are ‘True’. It only returns ‘False’ if both operands are ‘False’.

NOT Operator

• The NOT Operator is a unary operation, meaning it only requires one boolean value.
• It returns the opposite of the operand’s value. If the operand is ‘True’, it returns ‘False’, and vice versa.

XOR (Exclusive OR) Operator

• The XOR Operator, also known as the ‘Exclusive OR Operator’, is a binary operation.
• It returns ‘True’ only if one of its operands is ‘True’, but not both.

Understanding Boolean Operations in Programming

• Boolean operations form the basis of conditional statements in programming.
• They help with decision making in a program, enabling it to act differently under different circumstances.
• Boolean operations are essential for control flow mechanisms, such as if statements and loops.
• Understanding boolean operations is crucial in areas like search algorithms, where you need to make comparisons and test conditions.

Evaluation Order

• When performing operations, it’s essential to understand the order of precedence.
• ‘NOT’ has the highest precedence, followed by ‘AND’, then ‘OR’.
• To clarify the evaluation order, parentheses can be used to group operations together. Operations in parentheses will be carried out first.
