Answer 1

#include <iostream>
#include <utility>

using namespace std;

//Person class definition
class Person {
    //instance variable declaration
private:
    string name;
    int age{};
    char gender{};
public:
    //setter methods to set name,age and gender
    void setName(string pName) {
        name = std::move(pName);
    }

    void setAge(int pAge) {
        age = pAge;
    }

    void setGender(char pGender) {
        gender = pGender;
    }

    //getter methods to return name,age and gender
    string getName() {
        return name;
    }

    [[nodiscard]] int getAge() const {
        return age;
    }

    [[nodiscard]] char getGender() const {
        return gender;
    }
};

//Employee class definition
class Employee {
    //instance variable declaration
private:
    string employerName;
    float dailyWages{};
public:
    //setter methods to set employerName and dailyWages
    void setEmployerName(string eName) {
        employerName = std::move(eName);
    }

    void setDailyWages(float dWage) {
        dailyWages = dWage;
    }

    //getter methods to return employerName and dailyWages
    string getEmployerName() {
        return employerName;
    }

    [[nodiscard]] float getDailyWages() const {
        return dailyWages;
    }
};

/*Teacher class derived from Person class and Employee class with public

class Teacher : public Person, public Employee {
    //instance variable declaration

int main() {

    it consist the attributes name,age and gender*/

    t.setAge(42);
    t.setGender('M');
    /*set t's employerName and dailyWage using setter methods.(Since Teacher derived from
    Employee also,it consist the attributes employerName and dailyWage.
    Teacher derived from Person and Employee.So it is multiple inheritance*/
    t.setEmployerName("Thomas Mathew");
    t.setDailyWages(100);
    //set t's teacherGrade using setter method
    t.setTeacherGrade("grade 3");
    //print Teacher t's details using getter methods
    cout << "Teacher t's information..." << endl;
    cout << "Teacher t's name: " << t.getName() << endl;
    cout << "Teacher t's age: " << t.getAge() << endl;
