Question

Can anyone help me with this lab? Thanks

Exceptions Lab In this lab you will get practice with exceptions by adding them to a class that represents bank accounts. I have provided two files, BankAccount.h and BankAccount.cpp, which have the code for the class itself. Your task is to modify the code to have it throw exceptions under the conditions listed below, then write a main which uses try/catch blocks to display error messages when the bank account is used in ways that trigger exceptions. The bank account should throw exceptions under the following circumstances withdrawing a negative amount depositing a negative amount withdrawing more money than is present in the account setting a negative starting balance . . To practice throwing different kinds of exceptions, when withdrawing or depositing negative amounts of money, the code should throw an integer that is the negative amount. When withdrawing more money than it present the code should throw a string, and when setting a negative starting balance the code should throw a domain_error exception.

The BankAccount.h:

The BankAccount.cpp:
