//PyProperty(created on January 03,2022) program looks like:

/***
class Fruit:
    def __init__(self, fruit, price,qty):
        self.fruit = fruit
        self.set_price(price)
        self.set_qty(qty)

            raise ValueError('Quantity must be positive')
        self._qty = qty

//C++ equivalent of above program is:
