# Polymorphism

When a message can be processed in different ways is called polymorphism.

##### Polymorphism is of two types:

· Overloading: In method overloading method performs the different task at

the different input parameters with same method name and in same class.

· Overriding: Overriding a method is to change the behavior of the method for

the derived class. Overriding is done using inheritance and virtual functions.

##### Example

To explain the concept of overloading I have created two classes Poly and

abc(inherits poly).

```
//creating object of poly classpoly p= new poly();    public class poly    {     //these two functions,
      sum(), are overloaded.        public int sum(int x, int y)        {            return (x + y);        }        public virtual int sum(int x, int y, int z)        {            return (x + y + z);        }    }     public class abc : poly    {    //overriding function
      sum(), of base class poly        public override int sum(int x, int y, int z)        {            return (x + y + z + 10);        }    }
```

```
private void btnTwo_Click(object sender, EventArgs e)        {            int a, b,sum;            a= int.Parse(textBox1.Text);            b= int.Parse(textBox2.Text);           //calling sum(a,b) of poly            sum= p.sum(a, b);            MessageBox.Show("Sum of (Box 1 & 2): " + sum.ToString(), "Two parameters");        }         private void btnThree_Click(object sender, EventArgs e)        {            abc x1 = new abc();            int a, b, c,
            sum,sum1,sum2;            a = int.Parse(textBox1.Text);            b= int.Parse(textBox2.Text);            c= int.Parse(textBox3.Text);            poly p = new poly();           //calling sum(a,b,c) of poly            sum1=p.sum(a,b, c);           //calling override function sum()                       p= new abc();            sum2 = p.sum(a, b, c);            MessageBox.Show("Sum of (Box 1, 2 & 3): " + sum1.ToString(), "Three Parameters");            MessageBox.Show("Sum of (Box 1, 2 & 3): " + sum2.ToString(), "Three Parameters");        } 
```
