Chapter 4: Problem 5

Briefly describe how the \(\& \&\) operator works.

Short Answer

Expert verified
Short Answer: The "and" or && operator is a logical operator that operates on two boolean values. It returns 'true' if and only if both operands are 'true'. Otherwise, it returns 'false'. This means for the result to be 'true', both conditions have to be 'true'. The behaviour of the && operator is easy to understand when examined with its truth table.

Step by step solution

01

Definition

The \(\&\&\) operator is a logical operator, also known as the "and" operator. It takes two boolean inputs (true or false values) and returns a boolean value based on specific rules.
02

Truth Table

Understanding the behavior of the \(\&\&\) operator is easier if we look at its truth table, which shows all possible input combinations and the corresponding output. |\(A\) | \(B\) | \(A \&\& B\)| |----|----|----------| |true|true|true | |true|false|false | |false|true|false | |false|false|false |
03

Explanation

The \(\&\&\) operator returns true if and only if both of its operands are true. In all other cases (i.e., when at least one of the operands is false), the operator returns false. This is the reason why it's called the "and" operator, as both conditions need to be true for the final result to be true.
