Using 3rd variable class SwapTwoNumbersUsingTempVariable { public static void Main() { Console.WriteLine("/****** Program to swap 2 numbers using temporary variable *******/"); int a = 10, b = 20; Console.WriteLine(" Values before swapping a={0} , b={1}", a, b); int tempVar = 0; //temporary variable tempVar = a; a = b; b = tempVar; Console.WriteLine(" Values after swapping a={0} , b={1}", a, b); Console.ReadKey(); } }

Without using 3rd variable using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace Swapp_two_number_without_3rd_var { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { int a; int b; a = 1; b = 2; MessageBox.Show("Original numbers are" + a + ":"+ + b); a = a + b; b = a - b; a = a - b; MessageBox.Show("Swapping numbers are" + a + ":" + +b); } } }
