Inheritance Introduction c++


Problem Statement :


One of the important topics of Object Oriented Programming is Inheritance. Inheritance allows us to define a class in terms of another class, which allows us in the reusability of the code.Check out the code below:

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

The class Triangle has a function called triangle(). Now we create a class derived from the base class Triangle called Isosceles.

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

Now we can create a derived class object and use it to access the functions of the base class.

int main(){
    Isosceles isc;
    isc.isosceles();
    isc.triangle();
    return 0;
}

This code will print:

I am an isosceles triangle
I am a triangle

Now write a function in Isosceles class such that the output is as given below.

#include <iostream>
#include <algorithm>
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";
       }
    
       void description(){
          cout<<"In an isosceles triangle two sides are equal\n";
       }
};
int main(){
    Isosceles isc;
    isc.isosceles();
     isc.description();
    isc.triangle();
    return 0;
}

The Strange Function

One of the most important skills a programmer needs to learn early on is the ability to pose a problem in an abstract way. This skill is important not just for researchers but also in applied fields like software engineering and web development. You are able to solve most of a problem, except for one last subproblem, which you have posed in an abstract way as follows: Given an array consisting

Treeland is a country with n cities and n - 1 roads. There is exactly one path between any two cities. The ruler of Treeland wants to implement a self-driving bus system and asks tree-loving Alex to plan the bus routes. Alex decides that each route must contain a subset of connected cities; a subset of cities is connected if the following two conditions are true: There is a path between ever
