Define a class called Toy with private members name, and cost of type double. The class has the public members set(), a parameterized constructor with default values for the data members, and a destructor. The class includes a static data member totalCost of type double to calculate the total cost of all toys, and a static function get TotalCos). Define a class called Child with private members name. The class has the public members ser(), a parameterized constructor with default values for the data members, and a destructor. The class includes a static data member count of type int to count total number of children, and a static function gerCount(). Implement all member functions of both classes. Use the following driver produces the given sample of input/ atput: int main double avg: Child firstChild: Child secondChild; Child thirdChild; firstChild.set("Ali", 1); secondChild.set("Mariam", 2); thirdChild.set("Omar", 1); cout
