help pls C#

[dynw]

hi can someone help me to make a calculator as required?
Create class Calculator. This class must contain the following features:

constant PI
constructor that accepts two integers, operand1 and operand2
method for writing values ​​and operand2 operand1
methods for calculating the four operations - addition, subtraction, division and multiplication that will return the result of operand1 and operand2 operation on values
static methods for these operations, which accepts parameters as operands
method that calculates the surface area of the circle diameter circle operand1.
Create a console application that instantiates object of class Calculator, call all the methods and write the result of calculation.
pls thanks
sorry for my bad english

[thines01]

These instructions are very clear.
Have you written any part of this, yet?

No, I'm a beginner, I did something but not as required ... I want someone to help me ... thanks

Can you first make a Console App that says "Hello, World"?

Can you first make a Console App that says "Hello, World"?

yes

[dynw]

pls I need to school

[thines01]

I know you need this for school and you might be late on this, but there are things you need to understand especially if you plan to write code in the future (next semester).

Can you then add a class to that code called Calculator?

using System;

namespace DW_402600
{
   public class Calculator
   {
      //calculator code goes here
   }

   class Program
   {
      static void Main(string[] args)
      {
         // code that uses calculator goes here
         // Calculator calc = new Calculator(3,4);
         // More code goes here to show results.
      }
   }
}

[dynw]

no :( is my first year. I am a little confused

[thines01]

OK, good.
So take that frame and add your methods to it.
There will be four methods and at LEAST one constructor in the calculator class.

[dynw]

you can do the whole code for me?
or even half?
I would be grateful

hi
can u post any code for your basic mathematical operation ...like (add,Sub etc ) so that i can help you..

[dynw]

hi can someone help me .. say if my code is better?? not sure that I did good

using System;
using System.Collections.Generic;

That looks like it will work. :)
Remember to initialize your variables in the constructor.

Thank you very much for your help

you Can Add this Class :

 class Calc
    {

            public const double pi = 3.14;

            // Method To ADD The Two Operands......
            public static double add(double op1, double op2)
            {
                double res = op1 + op2;
                return res;


            }
            // Method To Subtaract The Two Operands......
            public static double subtarct(double op1, double op2)
            {
                double res = op1 - op2;
                return res;


            }
            // Method To Multiply The Two Operands......
            public static double multi(double op1, double op2)
            {
                double res = op1 * op2;
                return res;


            }
            // Method To Divided The Two Operands......
            public static double div(double op1, double op2)
            {
                double res = op1 / op2;
                try
                {
                    return res;
                }
                catch (Exception ex)
                {
                    return 0;

                }



            }
