# Can we make a program having structure or class under structure?

Yes, we can make a program having structure or class under structure.\

```
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks; namespace ConsoleApplication14{    struct demo    {             public
void fun1()        {            demo2
d2 = new demo2();            demo3
d3 = new demo3();                  
d2.fun2();           
Console.WriteLine("structure under structure is implemented
successfully");           
d3.fun2();           
Console.WriteLine("structure under class  is implemented successfully");        }        struct
demo2         {           
public void fun2()            {               
Console.WriteLine("Testing Comment");            }        }        class
demo3        {           
public void fun2()            {               
Console.WriteLine("Testing Comment");            }        }                   }    class Program
    {         static
void Main(string[] args)        {            demo
d1 = new demo();           
d1.fun1();            demo2
d2 = new demo2();            demo3
d3 = new demo3();            
d2.fun2();           
Console.WriteLine("Class under structure is implemented
successfully");           
d3.fun2();           
Console.WriteLine("Class under class is implemented
successfully");            
Console.ReadLine();                    }        struct
demo2        {           
public void fun2()            {               
Console.WriteLine("Testing Comment");            }        }        class
demo3        {           
public void fun2()            {               
Console.WriteLine("Testing Comment");            }        }            }}
