#includeThis program defines a `Person` class that has a `hashCode` function that combines the hash codes for the person's name and age. It then outputs the hash code for a particular person object. The package or library for the `String` class and its `hashCode` function is part of the C++ standard library.#include using namespace std; class Person { public: Person(string n, int a) : name(n), age(a){} string getName() const { return name; } int getAge() const { return age; } size_t hashCode() const { // combine hash values for name and age return (name.hashCode() * 31) + age; } private: string name; int age; }; int main() { Person person("John Doe", 30); cout << "Hash code for person: " << person.hashCode() << endl; return 0; }
