    int a = 5;
    public:
    A(){}
    protected:
    int getA(){
        return a;
    }
};
class B: public A{
    int b = 10;
    public:
    B(): A(){}

    int getB(){
        return b;
    }
};
class C: public B{
    int c = 15;
    public:
    C(): B(){}
    void display(){
        cout<<"Value of a: "<<getA()<<endl;
        cout<<"Value of b: "<<getB()<<endl;
        cout<<"Value of c: "<<c;

};
int main(){
    C c;
    c.display();
