C# Sharp Exercises: Function: Calculate the sum of the elements in an array

Sample Solution:

C# Sharp Code:

using System;

// Define a public class named 'funcexer5'
public class funcexer5
{
    // Define a public static method 'Sum' to calculate the sum of elements in an array
    public static int Sum(int[] arr1)
    {
        // Initialize a variable to store the total sum
        int tot = 0;

        // Loop through each element in the array
        for (int i = 0; i < arr1.Length; i++)
        {
            // Add each element to the total sum
            tot += arr1[i];
        }

        return tot; // Return the total sum of array elements
    }

    // Main method, the entry point of the program
    public static void Main()
    {
        // Initialize an array of integers with a length of 5
        int[] arr1 = new int[5];

        // Print a description of the program
        Console.Write("\n\nFunction : Calculate the sum of the elements in an array :\n");
        Console.Write("--------------------------------------------------------------\n");

        // Prompt the user to input 5 elements into the array
        Console.Write("Input 5 elements in the array :\n");
        for (int j = 0; j < 5; j++)
        {
            Console.Write("element - {0} : ", j);
            arr1[j] = Convert.ToInt32(Console.ReadLine());
        }

        // Call the 'Sum' method and display the sum of elements in the array
        Console.WriteLine("The sum of the elements of the array is {0}", Sum(arr1));
    }
}

Sample Output:

Function : Calculate the sum of the elements in an array :                                                    
--------------------------------------------------------------                                                
Input 5 elements in the array :                                                                               
element - 0 : 1                                                                                               
element - 1 : 2                                                                                               
element - 2 : 3                                                                                               
element - 3 : 4                                                                                               
element - 4 : 5                                                                                               
The sum of the elements of the array is 15
