Write a Month class that holds information about the month. Write exception classes for the following error conditions:• A number less than 1 or greater than 12 is given for the month number.• An invalid string is given for the name of the month.Modify the Month class so that it throws the appropriate exception when either of these errors occurs. Demonstrate the classes in a program.
C++ programming D.S.Malik 14-5
Write a program that prompts the user to enter a person’s date of birth in numeric form such as 8-27-1980. The program then outputs the date of birth in the form: August 27, 1980. Your program must contain at least two exception classes: invalidDay and invalidMonth. If the user enters an invalid value for day, then the program should throw and catch an invalidDay object. Follow similar conventions for the invalid values of month and year. (Note that your program must handle a leap year.)
Instructions:
Exception handing
Add exception handling to this game (try, catch, throw). You are expected to use the standard exception classes to try functions, throw objects, and catch those objects when problems occur.
At a minimum, you should have your code throw an invalid_argument object when data from the user is wrong.
File GamePurse.h:
class GamePurse
{
// data
int purseAmount;
public:
// public functions
GamePurse(int);
void Win(int);
void Loose(int);
int GetAmount();
};
File GamePurse.cpp:
#include "GamePurse.h"
// constructor initilaizes the purseAmount variable
GamePurse::GamePurse(int amount){
purseAmount = amount;
}
// function definations
// add a winning amount to the purseAmount
void GamePurse:: Win(int amount){
purseAmount+= amount;
}
// deduct an amount from the purseAmount.
void GamePurse:: Loose(int amount){
purseAmount-= amount;
}
// return the value of purseAmount.

return purseAmount;
