Problem 14
Define an exception class called tornadoException. The class should have two constructors, including the default constructor. If the exception is thrown with the default constructor, the method what should return "Tornado: Take cover immediately!". The other constructor has a single parameter, say, m, of the int type. If the exception is thrown with this constructor, the method what should return "Tornado: m miles away; and approaching!"
Problem 16
Suppose the exception class myException is defined as follows: class myException { public: myException() { message = "myException thrown!"; cout << "Immediate attention required!" << endl; } myException(string msg) { message = msg; cout << "Attention required!" << endl; } string what() { return message; } private: string message; } Suppose that in a user program, the catch block has the following form: catch (myException mE) { cout << mE.what() << endl; } What output will be produced if the exception is thrown with the default constructor? Also, what output will be produced if the exception is thrown with the constructor with parameters with the following actual parameter? "May Day, May Day"
Problem 17
If a function throws an exception, how does it specify that exception?
Problem 18
