Chapter 4.1, Problem 4.4CP

Explanation of Solution

Boolean expression:

• The Boolean expression is a logical statement which returns either “True” or “False” with the help of “if” statement.
• The relational operators are used to form the Boolean expression that is tested by an “if” statement.
• Some of the relational operators used in Boolean expression include “>” “<”, “==”, and so on.

Example:

The following program demonstrates how the Boolean expression is tested with “if…else” statement along with the relational operators:

//Define the header file

using System;

//Declare the namespace

namespace Conditional

{

        //Define the class name

        class Boolean

        {

            //Define the main function

            public static void Main(string[] args)

            {

                //Declare and assign the variable

                int number = 20;

                //Check whether "number" is greater than "0"

                ...
