  1. 1) Write a program to store five product information in object and display max price product details where product contains product id, ProductName, product price.

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;

    namespace shivaconcepttext
    {
    internal class product_Information
    {
    private int product_id;
    private string product_name;
    internal int product_price;

    internal void accept_information(int product_id,string product_name,int product_price)
    {
    this.product_id = product_id;
    this.product_name = product_name;
    this.product_price = product_price;
    }

    internal void diplay_information()
    {
    Console.WriteLine("id : {0} name : {1} price : {2}",product_id,product_name,product_price);
    }

    public static void Main()
    {
    product_Information[] info = new product_Information[2];
    for (int i = 0; i < info.Length; i++)
    {
    info[i] = new product_Information();
    Console.WriteLine("enter id");
    int id = Convert.ToInt32(Console.ReadLine());
    Console.WriteLine("Enter name");
    string name = Console.ReadLine();
    Console.WriteLine("enter price");
    int price = Convert.ToInt32(Console.ReadLine());
    info[i].accept_information(id, name, price);
    }

    int max = 0;
    for (int i = 0; i < info.Length; i++)
    {
    if (max < info[i].product_price)
    {
    max = info[i].product_price;
    }
    }
    Console.WriteLine("max price : " + max);
    }
    }
    }

  2. Write a program to calculate addition of two number but input data will be read from file and output data should also write on another file.

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;

    namespace shivaconcepttext
    {
    internal class file_aditiontwonumber
    {
    string file = "d://aditionfile.txt";
    int num1, num2;
    internal void createfile()
    {
    if (File.Exists(file))
    {
    Console.WriteLine("file already created");
    }
    else
    {
    FileStream fs = File.Create(file);
    fs.Close();
    Console.WriteLine("file created");
    }
    }

    internal void addcontent()
    {
    StreamWriter sw = new StreamWriter(file);
    if (File.Exists(file))
    {
    Console.WriteLine("enter number first");
    num1 = Convert.ToInt32(Console.ReadLine());
    Console.WriteLine("enter number second");
    num2 = Convert.ToInt32(Console.ReadLine());
    sw.WriteLine("first number is : " + num1);
    sw.WriteLine("second number id :" + num2);
    sw.Close();
    Console.WriteLine("number save succesfully");
    }
    else
    {
    Console.WriteLine("file not found");
    }
    }

    internal void readresult()
    {
    StreamReader sr = new StreamReader(file);
    if (File.Exists(file))
    {
    int sum = num1+ num2;
    Console.WriteLine("sum of num1 and num2 : " + sum);
    }
    else
    {
    Console.WriteLine("file not found");
    }
    }
    static void Main(string[] args)
    {
    file_aditiontwonumber obj = new file_aditiontwonumber();
    obj.createfile();
    obj.addcontent();
    obj.readresult();

    }
    }

  3. Write a program to manage possible inheritance between Customer, Product and Order class, where customer contain name and id, product contain name,id,price,and order contain id,name,orderdate?

    customer class : -

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;

    namespace shivaconcepttext
    {

    internal int id { get; set; }
    internal string name { get; set; }

    internal void accept_customer()
    {
    this.id = id;
    this.name = name;
    }

    internal void display_customer()
    {
    Console.WriteLine("id : {0} name : {1} price : {2}", id, name);
    }
    }
    }


    product class : -

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;

    internal void accept_product()
    {
    this.price = price;
    }

    internal void display_product()
    {
    Console.WriteLine("id : {0} name : {1} price : {2}", id, name, price);
    }
    }
    }


    order class : -

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;

    namespace shivaconcepttext
    {
    internal class order_inharitance : customer_inharitance
    {
    public string OrderDate { get; set; }

    internal void accept_order()
    {
    this.OrderDate = OrderDate;
    }

    internal void display_order()
    {
    Console.WriteLine("id : {0} name : {1} price : {2}", id, name, OrderDate);
    }
    }
    }

    display product class output : -

    static void Main(string[] args)
    {
    product_inharitance obj = new product_inharitance();
    obj.id = 1;
    obj.name = "vaishu";
    obj.price = "45000";
    obj.accept_product();
    obj.display_product();
