Question
I cant get this program to meet some of the requirements for my assignment i need a little help please.
1.The Account class must be an abstract class with two pure virtual functions, closeMonth
and accountString.
2. The balance, withdrawal and deposit manipulation must use the methods in the base
class Account.
3. Each action must display appropriate messages indicating that the action was
completed.
4. The closeMonth and accountString functions must be called polymorphically. This
means, they are called for each account without checking to see what kind of account it
is being called on.
5. An implication of the last point is that there will be a single array of Account objects,
some of which are Checking accounts and some of which are Savings accounts.
