Note: If you are new to C# and Console Application. Try to code First C# Program

Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code the program.

Practical Implementation:

using System;

namespace patternProblem.Simple_program
    class Simple5   //swap number using two variables
        static void Main(string[] args)
            Console.Write("Enter first number: ");
            int fn = Convert.ToInt32(Console.ReadLine());
            Console.Write("Enter second number: ");
            int sn = Convert.ToInt32(Console.ReadLine());


            Console.WriteLine("Before swapping a is : {0}", fn);
            Console.WriteLine("Before swapping b is : {0}", sn);
            fn = fn + sn;
            sn = fn - sn;
            fn = fn - sn;
            Console.WriteLine("After swapping a is : {0}", fn);
            Console.WriteLine("After swapping b is : {0}", sn);


The first input number here is 5 and second input number is 2. The program will swap numbers. The output is shown below:

Enter first number: 5
Enter second number: 2

Before swapping a is: 5
Before swapping b is: 2
After swapping a is: 2
After swapping b is: 5
