Sum of Array Elements

Write a C# Sharp program to compute the sum of the elements of an array of integers.

Visual Presentation:

C# Sharp: Basic Algorithm Exercises - Compute the sum of the elements of an given array of integers.

Sample Solution:-

C# Sharp Code:

using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
    class Program // Defining a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {
            // Output the result of the 'test' function with different integer arrays as arguments
            Console.WriteLine(test(new[] { 10, 20, 30, 40, 50 })); // Calling test method with array [10, 20, 30, 40, 50] and displaying the result
            Console.WriteLine(test(new[] { 10, 20, -30, -40, 50 })); // Calling test method with array [10, 20, -30, -40, 50] and displaying the result
        }     

        // Method to calculate the sum of the first five elements of an integer array
        public static int test(int[] a1)
        {
            // Return the sum of the first five elements of the array 'a1'
            return a1[0] + a1[1] + a1[2] + a1[3] + a1[4];
        } 
    }
}

Sample Output:

150
10

Flowchart:

Go to:

PREV : Same First or Last Element in Two Arrays.
NEXT : Rotate Array Left.
