Answer / amit
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.

Answer / mms zubeir
Though there are many answers which are all true to some
extent, I would like to conclude all these into two broad
categories:
1. Ad-hoc polymorphism
2. Parametric polymorphism
As the meaning of the names themselves suggests their usage.
If the range of actual types that can be used is finite
and the combinations must be specified individually prior
to use, it is called Ad-hoc polymorphism.
If all code is written without mention of any specific type
and thus can be used transparently with any number of new
types, it is called parametric polymorphism.
