Question

c++
Define polymorphism. What is the benefit of using pointers with polymorphic functions?

Answer 1

Polymorphism can be defined as a code that is processed or run multiple times to achieve the desired output. There are two types of polymorphism run-time(Method overriding) or compile-time(Method overloading).

Benefits of Polymorphism

• Code can be used multiple times
• A single variable can be used to store multiple data types
• Assist smooth compilation

E.g

#include <iostream> 
Using namespace std: 

class student {  
   public: 
   void show() {    
      cout << "Hello Welcome to class"; 
   } 
}; 

class School:public student { 
   public: 
   void show() {   
      cout << "Please Study well"; 
   } 
};  

int main() {   
   student x;        // Base class object 
   school y;        // Derived class object 
   x.show();   // student class method is called 
   y.show();   // school class method is called 
   return 0; 
} 

Output

Hello welcome to class

Please study well
