EE160 Programming for Engineers

A program that takes in the account type and account balance. The program returns whether or not a minimum balance fee should be charged to the account

The program prints a summary of all the accounts detailing the total number of accounts and total amount in all accounts

• input:
  • account holder (string)
  • account balance (decimal number)
  • account type (character)
  • exit program (character)
• output:
  • message telling the teller if the minimum balance fee should be charged or not ("A minimum balance fee needs to be charged to this account." or "A minimum balance fee does not need to be charged to this account."
  • message telling the teller if s/he has entered in an invalid account type
  • each account will also have a summary with the following information:
    • account holder information
    • percentage of the minimum balance fee charged compared to the account balance of each of the accounts
  • a file with the accounts summary containing the following information:
    • total number of accounts
    • total amount in all accounts
    • percentage of total minimum balance fees charged compared to the total balance of all the accounts
    • percentage of accounts that were charged a minimum balance fee
  • a file with a list of account balances entered by the teller

What are some questions the program needs to ask:
• it needs to check if the account is a saving account
• it needs to check if the account is a checking account
• it needs to check if the account balance is less than $1,000 for saving account
• it needs to check if the account balance is less than $500 for checking account
• it needs to check if the teller wants to exit the program

What are some tasks the program need to do:
• it needs to display a message to tell the teller to charge a minimum balance
• it needs to display a message to tell the teller to not charge a minimum balance
• it needs to continue reading in account balances and account types until the user wants to exit the program
• it needs to count the number of accounts
• it needs to total the amount of all the accounts
• it needs to calculate the percentage of minimum balance fees charged compared to the total amount of all the accounts
• it needs to calculate the percentage of minimum balance fee charged compared to the the balance on the account for each account
• it needs to calculate the adjusted balance after the minimum balance fee is accounted for
• it needs to list the account balances in a file
• it needs to display the account holder information
• it needs to output a file with the accounts summary information:
  • number of accounts
  • amount of all the accounts
  • percentage of minimum balance fees charged compared to the total amount of all the accounts
• it needs to make sure the account type entered is valid

How can we arrange the questions and tasks to develop an algoirthm (step-by-step procedure) that will meet our requirements?:

Some questions to ask:
• How can we simplify the problem?
• What order should the questions be asked?
• What order should the program tasks be done?

Using words:

• do
    get account holder information
    check if the account is a saving account and less than \$1000
      when yes, then tell the teller to charge the minimum balance fee
    when no, check if the account is a checking account and less than \$1000
      when yes, then tell the teller to charge the minimum balance fee
    otherwise
      check if the account is not a valid account type
        when yes, tell the teller that the account type is invalid
        otherwise, tell the teller to not charge the minimum balance fee
  
    check if the account type was valid
      when yes, then
        display account holder information
        display account summary for individual account
        update accounts summary information
        update list of account balances
    ask the user if there are more accounts to be checked
  while there are more accounts to be checked
  
  output accounts summary information to a file
  output list of account balances to a file
