    C# Program for an Addition of Whole Number in Alternative Way

    I have a Doubt in C# program. I was going through an program.
    This was the problem i faced.
    There is a whole number 7634
    So here Adding (73) & (64) i.e First Digit & Third Digit with Second digit & fourth digit. So answer will be 137

    I tried different techniques for creating this program. No use.
    So please suggest me the techniques or program for this one (C#)

    In this case logic you need follow,
    1. First split all the values.

    see the simple code for that below,

    string[] strNum = TextBox1.Text.Split(' ');
    string strFirstNum = strNum[0];
    string strSecNum = strNUM[1];
    string strLastNum = strNum[2];


    I believe once you split the value you will be able to add it. Let me know if you still require any help from me.

    You can use following code snippet for Addition of Whole Numbers in C#

    public class Addition
    public static void Main( string[] args )
    int num1;
    int num2;
    int sum;
    Console.Write( "Enter first integer: " );
    num1 = Convert.ToInt32( Console.ReadLine() );

    Console.Write( "Enter second integer: " );
    num2 = Convert.ToInt32( Console.ReadLine() );

    sum = num1 + num2;

    Console.WriteLine( "Sum is {0}", sum );


    Results Output

    Enter first integer: 50
    Enter second integer: 70
    Sum is 120

    Hi Mohamed,

    In this case, You need to split the numbers into digits. Please follow the below snippet:

    int number = 7634;
    string FirstNum;
    string SecondNum;
    string ThirdNum;
    string FourthNum;

    string Temp1;
    string Temp2;

    int Result;

    FirstNum = number.ToString().Substring(0, 1);
    SecondNum = number.ToString().Substring(1, 1);
    ThirdNum = number.ToString().Substring(2, 1);
    FourthNum = number.ToString().Substring(3, 1);

    Temp1 = FirstNum + ThirdNum;
    Temp2 = SecondNum + FourthNum;

    Result = Convert.ToInt32(Temp1) + Convert.ToInt32(Temp2);


    Hope this will help you.

    Hai Mohamed Sheik,
    You can use the below generic code where you can enter the number and then it will count and get the sum of even and odd digits:

    using System;

    namespace DemoOops
    class Program
    static void Main(string[] args)
    Console.WriteLine("please enter the number...");
    string originalNumber = Console.ReadLine().ToString();
    int i = 0;
    string x = string.Empty, y = string.Empty;
    foreach (char c in originalNumber.ToCharArray())
    if (i % 2 == 0)
    x += c.ToString();
    y += c.ToString();
    Console.WriteLine("First Number:" + x.ToString());
    Console.WriteLine("Second Number:" + y.ToString());
    Console.WriteLine("Sum is: " + (Convert.ToInt32(x) + Convert.ToInt32(y)));

    Hope it will be helpful to you.
