Homework SourseI need to create a bankAccount class checkingAccount class a
I need to create a bankAccount class, checkingAccount class, and a savingsAccount class. I understand how to create the base class for the most part, but I\'m having trouble creating the derived classes. I\'d appreciate any help I can get!
What I need to do:
a) Define the class bankAccount to store a bank customer\'s account number and balance. Suppose that account number is of type int, and balance is of type double. Your class should, at least, provide the following operations: set the account number, retrieve the account number, retrieve the balance, deposit and withdraw money, and print account information. Add appropriate constructors.
b) Every bank offers a checking account. Derive the class checkingAccount from the class bankAccount (designed in part (a)). This class inherits members to store the account number and the balance from the base class. A customer with a checking account typically receives interest, maintains a minimum balance, and pays service charges if the balance falls below the minimum balance. Add member variables to store this additional information. In addition to the operations inherited from the base class, this class should provide the following operations: set interest rate, retrieve interest rate, set minimum balance, retrieve minimum balance, set service charges, retrieve service charges, post interest, verify if the balance is less than the minimum balance, write a check, withdraw (override the method of the base class), and print account information. Add appropriate constructors.
c) Every bank offers a savings account. Derive the class savingsAccount from the class bankAccount (designed in part (a)). This class inherits members to store the account number and the balance from the base class. A customer with a savings account typically receives interest, makes deposits, and withdraws money. In addition to the operations inherited from the base class, this class should provide the following operations: set interest rate, retrieve interest rate, post interest, withdraw (override the method of the base class), and print account information. Add appropriate constructors.
d) Write a program to test your classes designed in parts (b) and (c)
Also, I need to create this class:
In C++, the largest int value is 2147483647. So, an integer larger than this cannot be stored and processed as an integer. Similarly, if the sum or product of two positive integers is greater than 2147483647, the result will be incorrect. One way to store and manipulate large integers is to store each individual digit of the number in an array. Design a class named largeIntegers such that an object of this class can store an integer of any number of digits. Add operations to add, subtract, multiply, and compare integers stored in two objects. Also add constructors to properly initialize objects and functions to set, retrieve, and print the values of objects.
Thanks in advance!
Solution
The following program is the answer to all your questions in a a very well defined manner and has comments for self understanding. It is compiled using dev c++ and runs smooth.
A cheque structure variable has been created for smooth transactions of cheques and encapsulation of cheque balance and number and passing and returning to and from functions.
