c++ The Lock class of the preceding problem has a small problem. It does not support combinations that start with one or more zeroes. For example, a combination of 0042 can be opened by entering just 42. Solve this problem by choosing a different representation. Instead of an integer, use a string to hold the input. Once again, the combination is hardwired. You will see in Section 9.6 how to change it. Complete the following file:

Product class has three private member fields: a product code (String), the product's price (double), and the number count of product in inventory (int). Implement the following Constructor and member methods: public Product(String code, double price, int count) - set the member fields using the three parameters public void setCode(String code) - set the product code (i.e. SKU234) to parameter code public String getCode() - return the product code public void setPrice(double p) - set the price to parameter p public double getPrice() - return the price public void setCount(int num) - set the number of items in inventory to parameter num public int getCount() - return the count public void addInventory(int amt) - increase inventory by parameter amt public void sellInventory(int amt) - decrease inventory by parameter amt Ex.
