Programming Language: C#

CheckingAccount class

You will implement the CheckingAccount Class in Visual Studio. This is a sub class is derived from the Account class and implements the ITransaction interface. There are two class variables i.e. variables that are shared but all the objects of this class. A short description of the class members is given below:

CheckingAccount

Class

Fields

$- COST_PER_TRANSACTION = 0.05 : double

$- INTEREST_RATE = 0.005 : double

- hasOverdraft: bool

Methods

+ «Constructor» CheckingAccount(balance = 0 : double, hasOverdraft = false: bool)

+ Deposit(amount : double, person : Person) : void

+ Withdraw(amount : double, person : Person) : void

+ PrepareMonthlyReport(amount : double, person : Person) : void

Fields:

  1. COST_PER_TRANSACTION – this is a class variable of type double representing the unit cost per transaction. All of the objects on this class will have the same value. This class variable is initialized to 0.05.
  2. INTEREST_RATE – this is a class variable of type double representing the annual interest rate. All of the objects on this class will have the same value. This class variable is initialized to 0.005.
  3. hasOverdraft – this is a bool indicating if the balance on this account can be less than zero. This private instance variable is set in the constructor.

Methods:

  1. public CheckingAccount( double balance = 0, bool hasOverdraft = false ) – This public constructor takes a parameter of type double representing the starting balance of the account and a bool indicating if this account has over draft permission. The constructor does the following:
    1. It invokes the base constructor with the string “CK-” and the appropriate argument.
    2. Assigns the hasOverdraft argument to the appropriate field.

  2. This definition hides the corresponding member in the parent class because the base class implementation is needed for this method as well as the Withdraw() method
    public new void Deposit( double amount, Person person ) – this public method takes two arguments: a double representing the amount to be deposited and a person object representing the person do the transaction. The method does the following:
    1. Calls the Deposit() method of the base class with the appropriate arguments
  3. public void Withdraw( double amount, Person person ) – this public method takes two arguments: a double representing the amount to be withdrawn and a person object representing the person do the transaction. The method does the following:
    1. Throws an AccountException object if this person in not associated with this account.
    2. Throws an AccountException object if this person in not logged in.
    3. Throws an AccountException object if the withdrawal amount is greater than the balance and there is no overdraft facility.
    4. Otherwise it calls the Deposit() method of the base class with the appropriate arguments (you will send negative of the amount)
  4. public override void PrepareMonthlyReport( ) – this public method override the method of the base class with the same name. The method does the following:
    1. Calculate the service charge by multiplying the number of transactions by the COST_PER_TRANSACTION (how can you find out the number of transactions?)
    2. Calculate the interest by multiplying the LowestBalance by the INTEREST_RATE and then dividing by 12
    3. Update the Balance by adding the interest and subtracting the service charge

    4. In a real-world application, the transaction objects would be archived before clearing.
      transactions is re-initialized (use the Clear() method of the list class)

This method does not take any parameter nor does it display anything

SavingAccount class

You will implement the SavingAccount Class in Visual Studio. This is a sub class derived from the Account class and implements the ITransaction interface. Again, there are two class variables. A short description of the class members is given below:

SavingAccount

Class

→ Account, ITransaction

Fields

$- COST_PER_TRANSACTION : double

$- INTEREST_RATE : double

Methods

+ «Constructor» SavingAccount(balance = 0 : double)

+ Deposit(amount : double, person : Person) : void

+ Withdraw(amount : double, person : Person) : void

+ PrepareMonthlyReport(amount : double, person : Person) : void

Fields:

  1. COST_PER_TRANSACTION – this is a class variable of type double representing the unit cost per transaction. All of the objects on this class will have the same value. This class variable is initialized to 0.05.
  2. INTEREST_RATE – this is a class variable of type double representing the annual interest rate. All of the objects on this class will have the same value. This class variable is initialized to 0.015.

Methods:

  1. public SavingAccount( double balance = 0 ) – This public constructor takes a parameter of type double representing the starting balance of the account. The constructor does the following:
    1. It invokes the base constructor with the string “SV-” and its argument.
  2. public new void Deposit( double amount, Person person ) – this public method takes two arguments: a double representing the amount to be deposited and a person object representing the person do the transaction. The method calls the Deposit() method of the base class with the appropriate arguments.
  3. public void Withdraw( double amount, Person person ) – this public method takes two arguments: a double representing the amount to be withdrawn and a person object representing the person do the transaction. The method does the following:
    1. Throws an AccountException object if this person in not associated with this account.
    2. Throws an AccountException object if this person in not logged in.
    3. Throws an AccountException object if the intended withdrawal amount exceeds the balance.
    4. Otherwise it calls the Deposit() method of the base class with the appropriate arguments (you will send negative of the amount)
  4. public override void PrepareMonthlyReport( ) – this public method override the method of the base class with the same name. The method does the following:
    1. Calculate the service charge by multiplying the number of transactions by the COST_PER_TRANSACTION (how can you find out the number of transactions?)
    2. Calculate the interest by multiplying the LowestBalance by the INTEREST_RATE and then dividing by 12
    3. Update the Balance by adding the interest and subtracting the service charge
    4. transactions is re-initialized (use the Clear() method of the list class)

This method does not take any parameters, nor does it display anything

Description: In this assignment, you will implement a deterministic finite automata (DFA) using C++ programming language to extract all matching patterns (substrings) from a given input DNA sequence string. The alphabet for generating DNA sequences is {A, T, G, C}. Write a regular expression that represents all DNA strings that begin with ‘A’ and end with ‘T’. Note: assume empty string is not a valid string. Design a deterministic finite automaton to recognize the regular expression. Write a program which...
