Chapter 3.4, Problem 3.21CP

Explanation of Solution

Given code:

//Declare and initialize variables

 Decimal pricePerFoot = 2.99m;

 double boardLenth =10.5;

 //Calculate the value

 decimal totalCost = boardLenth*pricePerFoot;

 Explanation:

 The above code throws an error because “*” cannot be applied to double and decimal operands. Here, the “boardLength” must be changed to decimal data type by using cast operator.

 Corrected code:

//Include libraries

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text.RegularExpressions;

//Define namespace

namespace program

{

    //Define class

    public class calculation

    {

        //Define main method

        public static void Main(string[] args)
