C#.Net find output programs (Structure) | set 2

Find the output of C#.Net programs | Structure | Set 2: Enhance the knowledge of C#.Net Structure concepts by solving and finding the output of some C#.Net programs.

Question 1:

using System;

namespace Demo
{
    struct Sample
    {
        public int A;
        public int B;

        public void init()
        {
            A = 10;
            B = 20;
        }
    }
    
    class Program
    {
        //Entry point of the program
        static void Main(string[] args)
        {
            int C = 0;
            Sample S;

            S.init();
            C = S.A + S.B;

            Console.WriteLine(C);
        }
    }
}

Question 2:

using System;

namespace Demo
{
    struct Sample
    {
        public int A;
        public int B;

        public Sample()
        {
            A = 10;
            B = 20;
        }
    }
    
    class Program
    {
        //Entry point of the program
        static void Main(string[] args)
        {
            int C = 0;
            Sample S= new Sample();

            C = S.A + S.B;

            Console.WriteLine(C);
        }
    }
}

Question 3:

using System;

namespace Demo
{
    struct Sample
    {
        int A;
        int B;

        public Sample(int a, int b)
        {
            A = a;
            B = b;
        }

        public int Sum()
        {
            return A + B;
        }

    }
    
    class Program
    {
        //Entry point of the program
        static void Main(string[] args)
        {
            int C = 0;
            Sample S= new Sample(10,20);

            C = S.Sum();

            Console.WriteLine(C);
        }
    }
}

Question 4:

using System;

namespace Demo
{
    struct Sample
    {
        int A;
        int B;

        public Sample(int A, int B)
        {
           this.A=A;
           this.B=B;
        }

        public int Sum()
        {
            return A + B;
        }

    }

    class Program
    {
        //Entry point of the program
        static void Main(string[] args)
        {
            int C = 0;
            Sample S= new Sample(10,20);

            C = S.Sum();

            Console.WriteLine(C);
        }
    }
}

Question 5:

using System;

namespace Demo
{
    struct Sample
    {
        int A;
        int B;

        public Sample(int A, int B)
        {
           this.A=A;
           this.B=B;
        }

        public int Sum()
        {
            return A + B;
        }

        public ~Sample()
        {
            Console.WriteLine("Destructor called");
        }
    }

    class Program
    {
        //Entry point of the program
        static void Main(string[] args)
        {
            int C = 0;
            Sample S= new Sample(10,20);

            C = S.Sum();

            Console.WriteLine(C);
        }
