Question

Please write a program in c# that meets the following specifications.  

Dominion Gas Corporation would like you to develop an application that helps them calculate the gas consumption bill of their customers. The application would first ask for the customer account number, the customer name and the type of account (residential or commercial). Then the application asks for the gas consumed during the past month by the customer in MCF (the unit used to indicate the amount of gas consumed). After gathering all this information the application calculates the bill based on the type of account (residential or commercial) and prints out the bill.

Technical Specifications:

The application will have two classes: Account and AccountTest

The Account class will have the following elements in it:

INSTANCE VARIABLES:

• Instance variable for account number and its property
• Instance variable customer name and its property
• Instance variable balance and its property

• Instance variable to store mcf
• Instance variable to store the rate of the account ($8.99 for residential, $11.99 for commercial)
• Instance variable to store usage charge for consumption of gas (mcf * rate)
• Instance variable to store municipal charge (2% of usage charge)
• Instance variable to store excise tax (5% of usage charge)

Constructor

• A constructor that accepts the account number and the customer name and uses those two values to initialize the appropriate instance variables (account number, customer name)

Methods

• A method that calculates the bill.
  • This method asks the user for the type of account (residential/commercial) for which the bill is to be calculated.
  • It also asks the user for the MCF used.
  • Based on these two pieces of information, it calculates the usage charge, municipal charge, excise tax and balance. It stores all these figures in their appropriate instance variables.
• A method that displays the bill.
  • This method simply prints out all the information about the bill such as the customer name, account number, the usage charge, municipal charge, excise tax and balance (see figures for samples of output)

The AccountTest class will have the following elements in it

the main method performs the following actions

asks for the account number, reads it in and stores it in a variable

Asks for the customer name, reads it in and stores it in a variable

uses these two pieces of information to create an object using the Account class's constructor

Calls the method that calculates the bill for the object created

calls the method that displays the bill for the object created.

Code

Account.cs Account class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Dominion_Gas_Corporation
{
class Account
{
private int account_number;
private string name;
private double balance;
private double mcf, rate, charge, municipal_charge, excise_tax;

public string Name
{
get { return name; }
set { name = value; }
}
public int AccountNumber
{
get { return account_number; }
set { account_number = value; }
}
public double Balance
{
get { return balance; }
set { balance = value; }
}

public Account(int num, string name)
{
AccountNumber = num;
Name = name;
}
public void CalculateCost()
{
int type;
Console.WriteLine("\n1) Residential\n2) Commercial");
Console.Write("Enter your account type: ");
type = Convert.ToInt16(Console.ReadLine());
if (type == 1)
rate = 8.99;
if (type == 2)
rate = 11.99;
Console.Write("Enter the amount of gas consumed during month in MCF: ");
mcf = Convert.ToDouble(Console.ReadLine());
charge = rate * mcf;

municipal_charge = charge * 0.02;
excise_tax = charge * 0.02;
balance = charge + municipal_charge + excise_tax;
}
public void printInfo()
{
Console.WriteLine("\n\nCustomer Name: " + name);
Console.WriteLine("Account Number: " + account_number);
Console.WriteLine("Usage Charge: $" + charge);
Console.WriteLine("Municipal Charge: $" + municipal_charge);
Console.WriteLine("Excise tax: $" + excise_tax);
Console.WriteLine("Balance: $" + balance);
}
}
}

AccounTest.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Dominion_Gas_Corporation
{
class AccountTest
{
static void Main(string[] args)
{
String name;
int number;
Console.Write("Enter youe name: ");
name = Console.ReadLine();
Console.Write("Enter your account number: ");
number = Convert.ToInt32(Console.ReadLine());

Account obj1 = new Account(number, name);
obj1.CalculateCost();
obj1.printInfo();
}
}
}
output
