Answer 1

#include <iostream>typedef struct {    double cost;    double profitRate;    double CalculateProfit () {        return cost* profitRate;    }    double CalculateSellingPrice() {        return CalculateProfit() + cost;    } } Product; int main() {    const int SIZE = 5;    Product* prod = new Product[SIZE];    std::cout <<"Enter cost and profit rate for 5 products.Profit rate is always smaller than 1." << std::endl;    for ( int i = 0; i < SIZE; i++ ) {        std::cout << "Enter data for product number " << i + 1 << std::endl;        std::cin >> prod[i].cost;        std::cin >> prod[i].profitRate;    }    for ( int i = 0; i < SIZE; i++ ) {        std::cout << "Product number " << i + 1 << std::endl;        std::cout << "Cost: " << prod[i].cost << "\n" << "Profit: " << prod[i].CalculateProfit() << "\n" << "Selling price: " << prod[i].CalculateSellingPrice() << std::endl << std::endl;    } }
