Question

I need help on the following question, as the textbook solution provided in Chegg does not work. Can someone provide an explanation as they write each line of code? Thank you!:

Exercise P7.1 in Big C++, 2nd Edition:

Implement a class Person with the following fields:

-the name

-a pointer to the person’s best friend (a Person*)

-a popularity counter that indicates how many other people have this person as their best friend

Write a program that reads in a list of names, allocates a new Person for each of them, and stores them in a vector. Then ask the name of the best friend for each of the Person objects. Locate the object matching the friend’s name and call a set_best_friend member function to update the pointer and counter. Finally, print out all Person objects, listing the name, best friend, and popularity counter for each.

Explanation / Answer

#include #include #include using namespace std; class Person { private: string name; int age; public: Person(string n, int a); string get_name()const; int get_age()const; void increment_age(); void print()const; }; Person::Person(string n, int a) { name = n; age = a; } string Person::get_name() const { return name; } void Person::increment_age() { age += 1; } void Person::print() const { cout
