Solution

Lion is a subclass of Animal . Animal is a superclass of Lion. the relationship between Lion and Animal is Inheritance.

#include <iostream>

using namespace std;

class Animal
{
   public:
       Animal(string name)
       {
           m_name = name;
           cout<<m_name<<endl;
       }
      
       protected:
           string m_name;
  
  
};

class Lion: public Animal
{
   public:
  
   Lion(string name): Animal(name){}
  
};

int main()
{
   Lion lion(\"King\");
   return 0;
  
}

output

King

second program

#include <iostream>

using namespace std;

// Base class
class Shape {
    public:
       void setWidth(int w) {
          width = w;
       }
       
       void setHeight(int h) {
          height = h;
       }
       
    protected:
       int width;
       int height;
};
// Derived class
class Rectangle: public Shape {
    public:
       int getArea() {
          return (width * height);
       }
};


int main(void) {
    Rectangle Rect;

    Rect.setWidth(5);
    Rect.setHeight(7);


    // Print the area of the object.
    cout << \"Total area: \" << Rect.getArea() << endl;


    return 0;
}

Total area: 35
