There are two types of polymorphism:-
1.Compile time polymorphism
This is achieved by:
- Function overloading
- Operator overloading
2.Run time polymorphism
This is achieved through inheritance and virtual functions.
In this, base class has one or more virtual functions which
are overridden in the derived class. And then base class
pointer is used to access base or derived class virtual
function.

Example:-

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

class derived {
public:
void func() {
cout << "In derived class" << endl;
}
};

int main(){
base *bp, b;
derived d;

bp = &b;
bp->func(); // base class func() will be called

bp = &d;
bp->func(); // derived class func() will be called
return 0;
}

Here, the decision to call base or derived class func() is
taken at run time.
