Write a C# Sharp program to find the sum of the first 10 natural numbers.

Visual Presentation:

Sample Solution:

C# Sharp Code:

using System;  // Importing necessary namespace

public class Exercise2  // Declaration of the Exercise2 class
{  
    public static void Main()  // Main method, entry point of the program
    {
        int j, sum = 0;  // Declaration of variables 'j' for iteration and 'sum' to store the total sum

        Console.Write("\n\n");  // Displaying new lines
        Console.Write("Find the sum of the first 10 natural numbers:\n");  // Displaying the purpose of the program
        Console.Write("----------------------------------------------");  // Displaying a separator
        Console.Write("\n\n");
	
        Console.Write("The first 10 natural numbers are:\n");

        for (j = 1; j <= 10; j++)  // Loop to calculate the sum of the first 10 natural numbers
        {
            sum = sum + j;  // Adding each number to the sum
            Console.Write("{0} ", j);  // Printing each natural number
        }

        Console.Write("\nThe Sum is : {0}\n", sum);  // Displaying the total sum of the first 10 natural numbers
    }
}

Sample Output:

Find the sum of first 10 natural numbers:                                                                     
----------------------------------------------                                                                
                  
The first 10 natural number are :                                                                             
1 2 3 4 5 6 7 8 9 10                                                                                          
The Sum is : 55
