LAB 3 Pseudo code

To insert new account:

Using For loop to add 3 accounts data structure

If all valid inputs by user, program displays successful else failed

To verify encapsulation:

User inputs one account for verification

Compares two fields and if its similar, prints message “Unsorted Optimized Array is not encapsulated” but if different, display message is “Unsorted Optimized Array is encapsulated”

To update account:

User inputs one account information.

Changes the interest rate of account

Update account to data structure

Update success or failed message print accordingly.

To delete an account

User inputs one account information.

Delete accounts.

Delete success or failed message print accordingly.

To show all accounts:

Prints all accounts in data structure.

When user inputs 0:

The Program terminates.

When user inputs anything else:

Program says invalid
