1. Add exception class objects to the Account classes from week 3 assignment, and add try-catch blocks to the code of all member functions where you think they may be needed.

2. Using exception handling semantics show what exceptions should be thrown from your class above if you try to withdraw more than there is in the account or above the accounts overdraft limit. Add code to throw the exception

3. Catch the exception thrown in 2 and handle it by printing an appropriate message to the screen informing the user of the exceeding the balance availability or overdraft limit.

The following is week 3 assinment
