using namespace std;

class FISH{ private: string name; double weight; double purchasedCost; int unit; double amount; char *date; public: FISH(){ time_t ttime = time(0); tm *gmt_time = gmtime(&ttime);

6. Derive a new class SHELLFISH from the FISH class and populate it using the data in the following Table: (10%) Shellfish Mussel Prawn Scallop Mean Weight (kg) 0.05 0.02 0.03 Purchase Cost (/kg) 4.00 6.25 6.50 Selling Price (/kg) 4 x Purchase Cost 4 x Purchase Cost 5 x Purchase Cost Units (min-max) 40-200 50-150 20-100 Expiry Date Entry Date + 2 Entry Date + 2 Entry Date + 2 7. Add a function to the "SHELLFISH class to calculate the number of packets of prawns in stock given that each packet holds 30 prawns (10%) 8. Add a function to enable the sale of prawns in packets, calculate and display the cost per packet of prawns and the profit from the sale of each packet, updating stock and income as necessary (10%) 9. Write main() code that uses the fish and shellfish classes to manipulate produce at a fish counter, with a user interface that facilitates sales and purchases (10%) 6.
