Can We inherit the interface into another interface?

Yes we can inherit the interface into another interface. It follows the same signature for inheritance as we use to inherit the class like:-

1.     Create first interface

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

public interface idef

{

   

     int sum(int p, int q);

     int mul(int p, int q);

    

}

2.     Create 2^nd interface and inherit first interface idef into this.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

public interface idef2 : idef

{

    int div(int p, int q);

}

3.     The class which implement the interface idef2 will give the definition to all m

The all member of both interfaces.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

/// <summary>

/// Summary description for Class2

/// </summary>

public class Class2: idef2

{

    public int sum(int x, int y)

    {

        return x + y;

    }

   public int mul(int x, int y)

    {

        return x * y;

   

    }

   public int div(int x, int y)

   {

       return x / y;

  

   }

}
