Solution

A class named Triangle is created which simply prints out a statement. Later another class named Icosceles is derived from the previous class which prints another statement. An object from the derived class is capable of calling the previous class functions without directly owning them.

#include <iostream>
using namespace std;

class Triangle{
    public:
        void triangle(){
            cout<<"I am a triangle\n";
        }
};

class Isosceles : public Triangle{
    public:
        void isosceles(){
            cout<<"I am an isosceles triangle\n";
        }
};

int main() {
    Isosceles isc;
    isc.isosceles();
    cout << "In an isosceles triangle two sides are equal\n";
    isc.triangle();
    return 0;
}
