Chapter 4: Problem 6

Briefly describe how the || operator works.

Short Answer

Expert verified
Provide an example in your response. Answer: The || (logical OR) operator is a binary operator used in programming to represent the logical disjunction between two boolean values. It evaluates to true if one or both of its operands are true, and false otherwise. For example, consider the following code: bool isSunny = true; bool isWarm = false; if (isSunny || isWarm) { // Go to the park } Here, the || operator checks if either isSunny or isWarm is true. Since isSunny is true and isWarm is false, the result of the || operator will be true, and the code block to go to the park will execute.

Step by step solution

01

Definition of || (Logical OR) Operator

The || (logical OR) operator is a binary operator used in programming to represent the logical disjunction between two boolean values. It evaluates to true if one or both of its operands are true and false otherwise.
02

Truth Table

In order to better understand how the || operator works, let's look at its truth table: Operand A | Operand B | A || B ----------| ----------|--------- true | true | true true | false | true false | true | true false | false | false As you can see from the table, if either operand A or operand B is true, then the result of A || B is true. If both are false, the result is false.
03

Example

Let's go through an example to illustrate how the || operator works in practice. Suppose we have the following code snippet: bool isSunny = true; bool isWarm = false; if (isSunny || isWarm) { // Go to the park } In this case, since isSunny is `true` and isWarm is `false`, the result of the || (logical OR) operator will be `true` since one of the operands is true. So, the code block to go to the park will execute.
