Develop a base class called Person with attributes like name, age, and gender. Derive a Voter class from Person, which extends its functionalities with attributes such as voter_id and hasVoted (a Boolean indicating whether the voter has cast their vote). Extend Person with a Candidate class, which introduces attributes like candidate_id and numVotes (representing the number of votes the candidate has received). Implement the described scenario in C++ using appropriate classes and methods to display the count of registered voters and the tally of votes cast.Test Case_1:Input:2Mr.Santhosh 18 MaleVID_101 YesCID_20CSE101 2Mr.Kavin 21 MaleVID_102 YesCID_20CSE102 1Output:number of voters registered: 2

Sure, here is the C++ code for the scenario you described:

#include<iostream>
#include<string>
using namespace std;

class Person {
public:
    string name;
    int age;
    string gender;
};

class Voter : public Person {
public:
    string voter_id;
    bool hasVoted;

    Voter(string name, int age, string gender, string voter_id, bool hasVoted) {
        this->name = name;
        this->age = age;
        this->gender = gender;
        this->voter_id = voter_id;
        this->hasVoted = hasVoted;
    }
};

class Candidate : public Person {
public:
    string candidate_id;
    int numVotes;

    Candidate(string name, int age, string gender, string candidate_id, int numVotes) {
        this->name = name;
        this->age = age;
        this->gender = gender;
        this->candidate_id = candidate_id;
        this->numVotes = numVotes;
    }
};

int main() {
    Voter v1("Mr.Santhosh", 18, "Male", "VID_101", true);
    Candidate c1("Mr.Santhosh", 18, "Male", "CID_20CSE101", 2);

    Voter v2("Mr.Kavin", 21, "Male", "VID_102", true);
    Candidate c2("Mr.Kavin", 21, "Male", "CID_20CSE102", 1);

    int voterCount = 0;
    int voteCount = 0;

    if (v1.hasVoted) {
        voterCount++;
        voteCount += c1.numVotes;
    }

    if (v2.hasVoted) {
        voterCount++;
        voteCount += c2.numVotes;
    }

    cout << "Number of voters registered: " << voterCount << endl;
    cout << "Tally of votes cast: " << voteCount << endl;

    return 0;
}

This code first defines a base class Person with attributes name, age, and gender. Then it defines two derived classes Voter and Candidate with additional attributes. In the main function, it creates instances of Voter and Candidate, counts the number of voters and the total votes, and then prints out the results.
