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 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 count of type int to count total number of children, and a static function getCount(). Implement all member functions of both classes. Use the following driver produces the given sample of input / output: int main() { double avg; Child firstChild; Child secondChild; Child thirdChild; firstChild.set("Ali", 1); secondChild.set("Mariam", 2); thirdChild.set("Omar", 1); cout
