(Account Class)

Create a class called Account that a bank might use to represent customers' bank accounts. Your class should include one data member of type double to represent the account balance. Your class should provide a constructor that receives an initial balance and uses it to initialize the data member. The constructor should validate the initial balance to ensure that it is greater than or equal to 0. If not, the balance should be set to 0 and the constructor should display an error message, indicating that the initial balance was invalid. The class should provide three member functions. Member function credit should add an amount to the current balance. Member function debit should withdraw money from the Account and should ensure that the debit amount does not exceed the Account's balance. If it does, the balance should be left unchanged and the function should print a message indicating "Debit amount exceeded account balance." Member function getBalance should return the current balance. Create a program that creates two Account objects and tests the member functions of class Account.

Try this:

using System;

public class Account

{

double balance;

public Account(double balance)

{

if (balance >= 0)

{

this.balance = balance;

}

else

{

balance = 0;

Console.WriteLine("Initial balance can't be less than zero. Zero used instead");

}

public void Credit(double amount)

{

if (amount > 0) // presumably

{

balance += amount;

}

public void Debit(double amount)

{

if (amount <= balance)

{

balance -= amount;

}

else

{

Console.WriteLine("Debit amount exceeded account balance.");

}

public double getBalance()

{

return balance;

}

class Test

{

static void Main()

{

Account acc1 = new Account(100);

Console.WriteLine("The intial balance of account 1 is {0}", acc1.getBalance());

acc1.Credit(100);

acc1.Debit(50);

Console.WriteLine("The final balance of account 1 is {0}", acc1.getBalance());

Console.WriteLine();

Account acc2 = new Account(-100);

Console.WriteLine("The intial balance of account 2 is {0}", acc2.getBalance());

acc2.Credit(30);

acc2.Debit(40);

Console.WriteLine("The final balance of account 2 is {0}", acc2.getBalance());

Console.ReadKey();

}
