C++ Hierarchical Inheritance
Hierarchical inheritance inherits the property of one base class in more than one derived class.
C++ Hierarchical Inheritance Example
#include <iostream>
using namespace std;
class Person {
char gender[10];
int age;
public:
void getPerson()
{
cout << "Age: "; cin >> age;
cout << "Gender: "; cin >> gender;
}
void dispPerson()
{
cout << "Age: " << age << endl;
cout << "Gender: " << gender << endl;
}
};
class Employee : public Person {
float salary;
public:
void getEmployee()
{
Person::getPerson();
cout << "Salary: Rs."; cin >> salary;
}
void dispEmployee()
{
Person::dispPerson();
cout << "Salary: Rs." << salary << endl;
}
};
class Student : public Person {
char level[20];
public:
void getStudent()
{
Person::getPerson();
cout << "Class: "; cin >> level;
}
void dispStudent()
{
Person::dispPerson();
cout << "Level: " << level << endl;
}
};
int main()
{
Person per;
Employee emp;
Student stu;
cout << "Student data" << endl;
cout << "Enter data" << endl;
stu.getStudent();
cout << endl << "Displaying data" << endl;
stu.dispPerson();
cout << endl << "Staff Data" << endl;
cout << "Enter data" << endl;
emp.getEmployee();
cout << endl << "Displaying data" << endl;
emp.dispPerson();
}
Output:
Student data
Enter data
Age: 10
Gender: f
Class: 5
Displaying data
Age: 10
Gender: f
Employee data
Enter data
Age: 30
Gender: m
Salary: 25000
Display data
Age: 30
Gender: m
