Sample Solution:

C# Sharp Code:

using System;

// Define a public class named 'funcexer6'
public class funcexer6
{
    // Define a public static method 'interchange' to swap the values of two integers
    public static void interchange(ref int num1, ref int num2)
    {
        int newnum;

        // Store the value of 'num1' in a temporary variable 'newnum'
        newnum = num1;
        // Assign the value of 'num2' to 'num1'
        num1 = num2;
        // Assign the value stored in 'newnum' (initially 'num1') to 'num2'
        num2 = newnum;
    }

    // Main method, the entry point of the program
    public static void Main()
    {
        int n1, n2;

        // Display a description of the program
        Console.Write("\n\nFunction : To swap the values of two integer numbers :\n");
        Console.Write("----------------------------------------------------------\n");

        // Prompt the user to enter the first number
        Console.Write("Enter a number: ");
        n1 = Convert.ToInt32(Console.ReadLine());

        // Prompt the user to enter the second number
        Console.Write("Enter another number: ");
        n2 = Convert.ToInt32(Console.ReadLine());

        // Call the 'interchange' method to swap the values of 'n1' and 'n2'
        interchange(ref n1, ref n2);

        // Display the swapped values of 'n1' and 'n2'
        Console.WriteLine("Now the 1st number is : {0} , and the 2nd number is : {1}", n1, n2);
    }
}

Sample Output:

Function : To swap the values of two integer numbers :                                                        
----------------------------------------------------------                                                    
Enter a number: 45                                                                                            
Enter another number: 65                                                                                      
Now the 1st number is : 65 , and the 2nd number is : 45
