Generally ‘+’ operator is used to add two numbers but in the following C# program there are add two numbers without using ‘+’ operator.

Program:

using System;

public class Program

{

 public static void Main()

 {

  int a=6,b=15;

  Console.Write('Sum of '+a+' and '+b+' is : ');

  while(b!=0)

  {

   a++;

   b--;		

  }		

  Console.WriteLine(a);

 }

}

Output:    Sum of 6 and 15 is : 21
