Question

This is my code :

the purpose is to add two big numbers ,First input two numbers in 2 array then swaping both and adding them , Console – Based ,

I’m a newbie in C# so please explain keeping in mind my few knowledge of codes

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Sum_Two_BIG_Numbes
{
    public class matrix
    {

        public int[] c;

        public void input(int[] a)
        {
            for (int i = 0; i < a.Length; i++)
            {

                a[i] = Convert.ToInt32(Console.ReadLine());

            }
        }
        public void Jamk(int[] a, int[] b, int[] c)
        {

            for (int i = 0; i < a.Length; i++)
            {
                int temp = a[i] + b[i];
                if ((temp < 10) && (c[i] != 1))
                {
                    c[i] = c[i] + temp;
                }
                else
                {
                    c[i] = c[i] + temp % 10;
                    c[i + 1] = c[i + 1] + temp / 10;

                }
            }


        }
        public void swap(int[] a)
        {

            for (int i = 0; i < a.Length; i++)
            {
                a[i] = a[a.Length - i];
            }

        }
    }
    class Program
    {
        public void Main(string[] args)
        {
            int[] a = new matrix();
            //int[] a = new int[30];
            int[] b = new int[30];
            int[] c = new int[30];
            Console.WriteLine("Enter First Number : ");
            matrix.input(a);


            Console.ReadLine();
        }
    }
}

I get this error “An Object Refrence is requiered for the non-static field . . . . ,”

Answer 1

matrix.input(a);

Where is matrix declared (it isn’t).

int[] a = new matrix();

Additionally, you cannot assign an instance of matrix to an int[]. There is no implicit conversion from one to the other. Though I can’t say this is a great design, what you wanted was something like this:

matrix a = new matrix();
a.c = new int[SomeSize];
// more code
a.input(b);  // or something similar...
