Sample Solution:

C# Sharp Code:

using System;

// Define a public class named 'funcexer3'
public class funcexer3
{
    // Define a public static method 'Sum' that takes two integer parameters and returns their sum
    public static int Sum(int num1, int num2)
    {
        int total;
        total = num1 + num2;
        return total;
    }

    // Main method, the entry point of the program
    public static void Main()
    {
        // Print a description of the program
        Console.Write("\n\nFunction to calculate the sum of two numbers :\n");
        Console.Write("--------------------------------------------------\n");

        // Prompt the user to enter a number and read the input as an integer
        Console.Write("Enter a number: ");
        int n1 = Convert.ToInt32(Console.ReadLine());

        // Prompt the user to enter another number and read the input as an integer
        Console.Write("Enter another number: ");
        int n2 = Convert.ToInt32(Console.ReadLine());

        // Calculate the sum by calling the 'Sum' method and print the result
        Console.WriteLine("\nThe sum of two numbers is : {0} \n", Sum(n1, n2));
    }
} 

Sample Output:

Function to calculate the sum of two numbers :                                                                
--------------------------------------------------                                                            
Enter a number: 25                                                                                            
Enter another number: 50                                                                                      
                                                                                                              
The sum of two numbers is : 75
