inheritance in cpp

Hello From Iqbal;
welcome to My Blog;in the program below i am going to use famous Object Oriented Programming Properties i.e.

•   Inheritance,
•   Encapsulation 
•  Method Overriding

feel free to comment if you have any question(s).




#include <iostream>

using namespace std;


class Person{    // person class , the base class from whihc further classes will inherit
private :
// encapsulated private members(data fields)
string profession;
int age;
public:
Person(){

}
void setAge(int a){    //setters ( mutators)
this->age=a;
}
void setProfession(string prof){
this->profession = prof;
}
int getAge()  {  //getters (accessors)
return age;
}
string getProfession()  {
return profession;
}

void display(){

cout<<"my Profession is"<<profession<<"\n";
cout<<"my age is: "<<age<<"\n";
walk();
talk();
} 
void walk(){
cout<<" i can walk"<<"\n";

}
void talk(){
cout<<"i can talk"<<"\n";
}
};

class MathsTeacher   : public Person{ //inherited from person base class

public : 
MathsTeacher(){
setAge(23);
setProfession("Teacher");
}

void display(){                                    //method overriding from super class  
cout<<"my Profession is:"<<getProfession()<<"\n";
cout<<"my age is: "<<getAge()<<"\n";
walk();
talk();
teachMaths();
}
void teachMaths(){
cout<<"i can teach Maths"<<"\n";
}
};

class Footballer   : public Person{

public : 
Footballer(){
setAge(19);
setProfession("FootBaller");
}

void display(){ //method overriding from super class 
cout<<"my Profession is: "<<getProfession()<<"\n";
cout<<"my age is: "<<getAge()<<"\n";
walk();
talk();
playFootball();
}
void playFootball(){
cout<<"i can Play Football"<<"\n";
}
};




int main(int argc, char** argv) {
MathsTeacher teacher;

teacher.display();
Footballer footballer;
footballer.display();
return 0;
}
