Write a program in C++ which creates class named as

·        Item   

This class should contain following members

o       stock   //forstock quantity of a certain item

o       quantitypurchased    //for quantity to be purchased ina customer’sorder        

This can be checked by comparingquantity_purchased with stock. If the quantity to be purchased ismore than the stock; an exception should be thrown.

To throw exception, you need tocreate another class named as

·        Exception

In main create an object ofclass Item and call the order method inside the try block. You cancheck in the definition of the method order () whether stock isless than quantity purchased. If it is true, then throw exceptionthat displays message saying;

      Thereis not enough stock

        Therequired quantity of item is available in thestock

SampleOutput1:

There is not enough stock  

(if the stock is less than quantitypurchased)

Sample Output2:

The required quantity of item is available inthe stock
