Types of polymorphism in C++ with example

Hello, student today we learn about How many types of polymorphism in C++ with example and how polymorphism performs its task in C++. types of polymorphism in C with example

Polymorphism in C++ with example

#include <iostream>
using namespace std;

class base {
public:
virtual void print()
{
cout << "print base class" << endl;
}

void show()
{
cout << "show base class" << endl;
}
};

class derived : public base {
public:
void print()
{
cout << "print derived class" << endl;
}

void show()
{
cout << "show derived class" << endl;
}
};

int main()
{
base* bptr;
derived d;
bptr = &d;

// virtual function, binded at runtime
bptr->print();

// Non-virtual function, binded at compile time
bptr->show();
}

Output

print derived class

show base class

What is Polymorphism

We have a pointer holding the object of the derived class, virtual functions will bind at run time, which means what overrides the base class virtual function will be called, and non-virtual functions will be called as per normal object

DISCUSSION

yes, I am able to understand runtime polymorphism and compiler time polymorphism.

Another issue is if i change statement to B& ra1= static_cast(objB); then compilation error.. it’s upcast and upcast is safe… but changing the type of ra1 causes compile-time error why?

Ans:- it should complain coz the derived class should not be able to access the base class.

Polymorphism in C++

In simple words, polymorphism is a Role or character of things, another word A kid made each time different role like Student, son, friend, boys, etc.
