HOMEWORK

1. As with all projects in this course, your program’s output will display your name, your EUID, your e-mail address, the department name, and course number. This means that your program will print this information to the terminal (see the sample output).
    
2. Declare and initialize the following constants and variables.
    
   • A global floating-point constant of type double to store the minimum balance for the
     business account initialized to 10000.00.
      
   • A global floating-point constant to of type double to store the minimum balance for the
     personal account initialized to 1000.00.
      
   • A global integer constant of type integer to store the length of account number and
     initialize it to 6.
      
   • A global integer constant of type integer to store the maximum number of transactions
     and initialize it to 20.
      
3. Declare an enumeration constant with values Business and Personal and assign integer values 0
   and 1 to the data items, respectively. They represent the type of bank account.
    
4. Declare another enumeration constant with values Process, Display and Quit, and assign suitable integer values 1, 2 and 3 to the data items, respectively. They represent menu choice presented
   to the user.

function named getName which gets the name on the bank account. Inside the function: Using a suitable message, prompt the user for the name on the account. The name can have multiple words.
Only alphabets (A-Z or a-z) and whitespaces are permitted in the account name. 

o If the user enters any other characters in the name, you need to generate an error message and ask for the name again. 

o Yourprogrammustkeeponaskingtheusertoenterthenameuntiltheuserentersit correctly.(SEE SAMPLE OUTPUT 1) 

The user may type the name in either uppercase or lowercase, but you need to convert every initial to uppercase. (SEE SAMPLE OUTPUTS)
This function will be called by the main function. 

function named getAccountNumber which get the account number. Inside the function: Using a suitable message, prompt the user for the number of the account.
The account number must be a 6-digit number. 

• If the user enters an account number with more than 6 digits generate an error message and ask the user to enter the number again.
   
• Only numbers 0-9 are permitted in the account number. If the user enters an account number with non-numeric characters, generate an error message, and ask the user to enter the number again.
   
• Your program must keep on asking the user to enter the number until the user enters it correctly. (SEE SAMPLE OUTPUTS 1 and 2)
   
• This function will be called by the main function.
   

7. Write a function named encrypt_num. This function must receive the account number using a string variable and encrypt the account number. Inside this function: 

• Declare an array of integers with size equal to the length of the account number.
   
• Using a loop of your choice, populate the array with seeded randomly generated numbers
  between 10 and 20 inclusive.
   
• In a second loop, add the randomly generated number to the characters in the account
   

• 

8. Write a

number to offset each character by the random value.
oStore the new characters in a different string. This new string is now your encrypted 

account number.
This function will be called by the main function. 

function named display_transactions. It accepts four parameters:
A 2D array of type double named transactions that stores the transactions performed on the accounts. The number of columns this 2D array is 2. The first column stores the business transactions while the second column stores the personal transactions. The maximum number of rows is limited to the maximum number of transactions declared globally, but note that the account may not have values for all 20 transactions. Also note that the number of personal and business transactions that are actually performed can be different.
An integer that represents the number of transactions to display.
An enum variable that determines whether the account is a Business account or a Personal Account.
A Boolean variable that determines if the transactions needed to sorted while displaying. The default value of this Boolean is false.
Inside this function: 

o Display the content of the transactions array that relates to the correct account type – Business and Personal (display the correct column, not both columns). 

o Sort if the default value has been overridden with true when this function is called.
o Your numeric data must have two numbers after the decimal point and a $ sign in front 

of the number (for example, $1375.85).
• This function will be called by the displayAccount function. 

9. Write a function named displayAccount.
• This function accepts three parameters.

• 

• 

o A 2D array of type double named transactions that stores the transactions performed on the accounts. 

o An integer that represents the number of business transactions to display.
o An integer that represents the number of personal transactions to display.
Inside this function:
o Using a suitable message, ask the user which account needs to be displayed – Business 

or Personal.
o Using a suitable message, ask the user if the display needs to be sorted.
o Based on the account type selected by a user, design a switch-case block with a default 

case, to implement the following features. 

• ➢  You must use the enumeration constants to set up your cases.
   
• ➢  You must use a variable of your enumeration constant type for switching control.
   
• ➢  If the user chooses a Business account, call function display_transactions with
  suitable value of parameters.
   
• ➢  If the user chooses a Personal account, call function display_transactions with
  suitable value of parameters.
   
• ➢  If the user enters a wrong choice, use the default case to provide an error message
  and ask the user to make the choice again.
   
• ➢  Your program needs to keep on asking the user for the choice until the user chooses
  a correct choice. (SEE SAMPLE OUTPUT 1) This function will be called by the main function.
  function named process_account.
  It accepts five parameters:
  o A 2D array of type double named transactions that stores the transactions performed
  on the accounts.
  oAn integer that represents the number of business transactions that has been
  processed.
  oAn integer that represents the number of personal transactions that has been
  processed.
  o A double that represents the current business account balance.
  o A double that represents the current personal account balance.
  Inside this function:
  Ask the user to choose which account the user wants to access – Business or Personal.
  o Use a suitable integer value to get the choice from the user.
  Based on the choice of the user, design a switch case block to implement the following requirements.
  o You must use the enumeration constants to set up your cases.
  o You must use a variable of your enumeration constant type for switching control.
  o If the user chooses a Business account
   
• ➢  Prompt the user for a transaction to process. The transaction can be a positive or a negative value. Positive transactions are deposits and negative transactions are withdrawals.
   
• ➢  If the current balance falls below the required minimum balance for a business account, there is a 10$ penalty (decrease current balance by $10 for every new
   

transaction) until the current balance updates to at least the minimum required 

balance. (SEE SAMPLE OUTPUT 5)
➢ If the current balance is below the minimum required balance, remind the user that 

the account is losing 10$ for every transaction using a suitable message. (SEE 

SAMPLE OUTPUT 5) 

o If the user chooses a Personal account 

• ➢  Prompt the user for a transaction to process. The transaction can be a positive or a
  negative value. Positive transactions are deposits and negative transactions are
  withdrawals.
   
• ➢  If any transaction drops the current balance below the minimum personal balance,
  the transaction will be denied with a suitable message to the user.
   
• ➢  Note that for personal accounts the current balance will never be less than the
  minimum balance and hence there are no provision of penalties either.
   

o If the user enters a wrong choice, use the default case to provide an error message and 

ask the user to make the choice again.
➢ Your program needs to keep on asking the user for the choice until the user chooses 

a correct choice. (SEE SAMPLE OUTPUT 1)
oDisplay the current balance in either case after each successful transaction. (SEE 

SAMPLE OUTPUTS) 

➢ Your numeric data must have two numbers after the decimal point and a $ sign in front of the number (for example, $1375.85). 

o This function needs be able to process more than one transaction.
oAfter successfully processing a transaction, ask the user if the user wants to process 

another transaction.
o If the user chooses to process another transaction, use a suitable loop to ask the user 

about the type of account and the transaction to process. (SEE SAMPLE OUTPUTS )
o If the user chooses to process additional transactions, the previous transactions should 

not be overwritten.
o Assume the user will not perform more than 20 transactions on either account. 

• This function will be called by the main function. 

11. Inside your main function: 

• Declare a 2D array of doubles to store the transactions performed on the account.
   
• Display a menu for the user (SEE SAMPLE OUTPUT) that provides the user three choices.
  o Process an account
  o Display the transactions on an account. o Quit the program
   
• Declare a double variable to store the current personal account balance and initialize it with the value 1000.00.
   
• Declare a double variable to store the current business account balance and initialize it with the value 10000.00.
   
• Declare two integer variables to store the number of business transactions and the number of personal transaction and initialize both with 0.
   
• Declare a string variable to store the name on the account.
   

o Call the getName function and pass the string variable for name to get the name. 

• Declare a string variable to store the account number.
  o Call the getAccountNumber function and pass the string variable for account number to get the account number.
   
• Using a suitable message, ask the user to make the menu choice using an integer variable.
   
• Based on the value entered by the user for menu choice, design a switch-case block to
  implement the following requirements.
  o You must use the enumeration constants to set up your cases.
  o You must use a variable of your enumeration constant type for switching control. o If the user chooses to process an account
  ➢ Call the function processAccount with suitable parameters. o If the user chooses to display an account
  ➢ Display the name with suitable message. Make sure the displayed name follows all requirements of Step 5.
  ➢Display the encrypted account number with suitable message. Call the encrypt_num function with appropriate arguments to encrypt the account number.
  ➢ Call the function displayAccount with appropriate arguments. o If the user choose to quit the program.
  ➢ Exit the program with a suitable message.
  o If the user chooses anything else, execute the default case to notify the user an incorrect
  choice.
   
  • ➢  Using a suitable loop, ask the use for the choice again.
     
  • ➢  Your program must keep on looping until the user enters the correct choice. (SEE
    SAMPLE OUTPUT 2)
     

1. Your program source code should be named “euidProject2.cpp”, without the quotes.
   where euid should be replaced by your EUID.
    
2. Your program will be graded based largely on whether it works correctly on the CSE machines (e.g., cse01, cse02, …, cse06), so you should make sure that your program compiles and runs on a CSE machine.
    

DESIGN (ALGORITHM): 

On a piece of paper (or word processor), write down the algorithm, or sequence of steps, that you will use to solve the problem. You may think of this as a “recipe” for someone else to follow. Continue to refine your “recipe” until it is clear and deterministically solves the problem. Be sure to include the steps for prompting for input, performing calculations, and displaying output. 

You should attempt to solve the problem by hand first (using a calculator as needed) to work out what the answer should be for a few sets of inputs.
Type these steps and calculations into a document (i.e., Word, text, or PDF) that will be submitted along with your source code. Note that if you do any work by hand, images (such as pictures) may be used, but they must be clear and easily readable. This document shall contain both the algorithm and any supporting hand-calculations you used in verifying your results.
