I have an assignment that isn't due till a few days, I'm just trying to get a head start.
So I have a program that is supposed to make "CheckingAccount.h" inherit from "BankAccount.h". I have written up the code and I am error free! But one of my functions for "setTransactionFee" or "getTransactionFee" will not do its job correctly. I am not expecting someone to write out the code for the function(even though that would be awesome!), but any ideas or help would be appreciated.
Here is what the output should look like...
1 2 3 4 5 6 7 8 9 10 11 12 13 14
Welcome to your bank
1. Make a deposit
2. Make a withdrawal
3. Set the account name
4. Set the account number
5. Set the transaction fee
6. Display account information
7. Exit
Please enter your choice: 6
Account Information
Number:23456
Name:Joe Smith
Balance:49.00
Transaction Fee:1.00
This is the code I have written up already..
Following includes:
-Bank.cpp
-BankAccount.h (SUPER CLASS)
-CheckingAccount.h (CHILD CLASS)

Well, for starters, you don't seem to be calling "setTransactionFee" or "getTransactionFee" anywhere in the code you've posted. How can you tell whether they're doing the right thing?
