C++ program to test inheritance through triangle class
Suppose we want to make one Triangle class and another child class called Isosceles. The triangle class has a function that prints that the object is of type triangle, and Isosceles has two functions to show that it is an isosceles triangle and one description. We also need to call the parent class function through Isosceles class object. There is no such proper input, we just call functions in proper way.
So, if the input is like define an object called trg, then call trg.isosceles(), trg.description(), trg.triangle()., then the output will be
This is an isosceles triangle
There are two sides are equal in an isosceles triangle
This is a triangle
To solve this, we will follow these steps −
Define the first Triangle class with public/protected function triangle()
Define Isosceles class with public inheritance where two methods are present called isosceles() and description()
Example
Let us see the following implementation to get better understanding −
#include <iostream>
using namespace std;
class Triangle{
public:
void triangle(){
cout<<"This is a triangle" << endl;
}
};
class Isosceles : public Triangle{
public:
void isosceles(){
cout<<"This is an isosceles triangle" << endl;
}
void description(){
cout<<"There are two sides are equal in an isosceles triangle" << endl;
}
};
int main(){
Isosceles trg;
trg.isosceles();
trg.description();
trg.triangle();
}
Input
Isosceles trg; trg.isosceles(); trg.description(); trg.triangle();
Output
This is an isosceles triangle There are two sides are equal in an isosceles triangle This is a triangle
