Assume MyClass defines two nested exception classes BadNumbe

Assume MyClass defines two nested exception classes, BadNumber and BadString. Also, assume that MyClass\'s method doSomething() throws these exceptions under certain error conditions, and returns without throwing anything when it decides no error has occurred. We call doSomething four times in a try/catch block: MyClassB a; try {a.doSomething(); a.doSomething(); a.doSomething(); a.doSomething();} catch (MyClass:: Bad Number) {cout
