/*Problem3: Define a class Item1 with data members code, qty and price and class Item2 with data members code and value.
(Hint: code = code, value = qty*price). Use the constructor in Item2 class to change the Item1 type data to Item2 type.
Your code should be able to execute the statement I2=I1 (where I1 and DI2 are objects of respective item class).*/
