This can be done by using 'base' keyword in C# language. For eg;

An abstract class is coded as follows:

abstract class AbstractDemo
{
public abstract void Habits();

public virtual void hello()
{
Console.WriteLine("Hello DerievedAbstract class,
hello()");
}

public void adddet()
{
Console.WriteLine("Hello Everybody...");
}
}

Then, I have created a derieved class of this class as:

class DerievedAbstract : AbstractDemo
{
public override void Habits()
{
Console.WriteLine("Hello DerievedAbstract class");
}

public override void hello()
{
base.adddet();
Console.WriteLine("Hello() is a function....");
}

new public void adddet()
{
Console.WriteLine("Hello Everybody....derieved
class");
}
}

In the Main() function, the object of Derieved class is
created as:

class classmain
{
public static void Main(string[] args)
{
DerievedAbstract ab = new DerievedAbstract();
ab.Habits();
ab.hello();
Console.ReadLine();
}
}

Give an example where we have to specifically use C programming language and C++ programming language cannot be used?

class CTest { public: void someMethod() { int nCount = 0; cout << "This is some method --> " << nCount; } }; int main() { CTest *pctest; pctest->someMethod(); return 0; } It will executes the someMethod() and displays the value too. how is it possible with our creating memory for the class . i think iam not creating object for the class.
